[0002] With the development of integrated circuit technology, various electronic devices are constantly enriched. In order to reduce the return rate, the manufacturers of electronic devices will configure error correction modules for components prone to failure in electronic devices. When the components configured with error correction modules have error outputs, the error correction modules will correct the error outputs, thereby ensuring the quality of the electronic devices and reducing the return rate of the devices.

[0003] However, during production and long-term use, it is impossible to avoid the failure of error correction modules. When the error correction modules fail, the data read from the corresponding components by the error correction modules will be incorrect, and after the error correction modules send the incorrect data to the chips, the chips will execute incorrect functions using the incorrect data. When the chips are applied to high-risk industries, incorrect function execution of the chips will cause serious life and property losses. SUMMARY

[0004] Embodiments of the present application provide a method and device for detecting an error correction module, an electronic device, and a storage medium, which can timely detect the failure of the error correction module and ensure the accuracy of data transmission of the error correction module.

[0019] In a fourth aspect, a computer storage medium is provided, and the computer storage medium stores a computer program, and the program is executed by a processor to implement the error correction module detection method provided by any of the embodiments of the present application.

[0020] The technical solution of this embodiment involves an error correction verification module acquiring error correction function verification data and error correction position data for verifying the error correction function of the error correction module. This error correction function verification data is then sent to the error correction module, which generates verification bit data to be verified based on the error correction array data and error correction verification bit data within the error correction function verification data. After obtaining the verification bit data to be verified, the error correction verification module determines the target error correction bit association data of the error correction array data based on the error correction array data and the verification bit data to be verified. Finally, the error correction function verification result of the error correction module is determined based on the target error correction bit association data and the error correction position data. Because the target error correction bit association data can reflect the status of the potential error correction function of the error correction module, and the error correction position data can reflect the data position of the erroneous data that can be identified when the error correction module is functioning normally during error correction function verification, the error correction verification module can accurately determine the abnormal state of the error correction function of the error correction module based on the target error correction bit association data and the error correction position data, thereby ensuring the accuracy of the output data of the error correction module. This solves the problem in the prior art that the error correction module faults cannot be detected in time due to the lack of error correction function detection, and the problem that the accuracy of the error correction module data transmission cannot be guaranteed. It can detect the faults of the error correction module in time and ensure the accuracy of the data transmitted by the error correction module. Attached Figure Description

[0029] Embodiment One

[0030] Figure 1 is a flowchart of a method for detecting an error correction module according to an embodiment of the present application. The embodiment can be applied to detecting the error correction function of an error correction module. The method can be performed by an error correction module detection device, which can be implemented by software and / or hardware and can be integrated in an electronic device. For example, the error correction module detection device can be an error correction verification module. Accordingly, as shown in Figure 1 the method includes the following operations:

[0031] S110, obtaining error correction function verification data and error correction position data for verifying the error correction function of the error correction module.

[0032] The error correction verification module can be a module capable of verifying the error correction function of a device, a device, and a module. The error correction module can be a module with an error correction function, which is used to check and correct errors in received data. The error correction function verification can be a verification operation of the error correction verification module on the error correction function of the error correction module. The error correction function verification data can be data sent by the error correction verification module to the error correction module for verifying the error correction function of the error correction module. The error correction function verification data can include error correction array data and error correction check bit data. The error correction array data can be part of the data required by the error correction module for verification, which is required by the error correction verification module to verify the error correction function of the error correction module. The error correction check bit data can be verification data corresponding to the error correction array data, which is used to detect the correctness of the error correction array data. The error correction position data can be used to represent the data position of the error data that can be recognized by the error correction module with normal error correction function when verifying the error correction function of the error correction module.

[0033] In the embodiment of the present application, the error correction verification module needs to first determine the error correction function verification data for verifying the error correction function of the error correction module before verifying the error correction function of the error correction module.

[0034] The error correction checking module can generate error correction function checking data according to the checking requirement of the error correction module, or obtain data from other devices, and then perform data processing on the obtained data to obtain a data processing result, so as to further take the data processing result as the error correction function checking data.

[0035] In S120, the error correction function checking data is sent to the error correction module, so that the error correction module generates to-be-checked solution checking bit data according to the error correction array data and the error correction checking bit data.

[0036] The to-be-checked solution checking bit data can be checking data calculated by the error correction module according to the error correction array data and the error correction checking bit data, and is used to judge whether the error correction function of the error correction module is normal.

[0037] In the embodiment of the present application, the error correction checking module can send the obtained error correction function checking data to the error correction module. After receiving the error correction function checking data, the error correction module can calculate the to-be-checked solution checking bit data according to the error correction array data, the error correction checking bit data and the algorithm for calculating the checking data, and send the to-be-checked solution checking bit data to the error correction checking module.

[0038] In S130, target error correction bit related data of the error correction array data is determined according to the error correction array data and the to-be-checked solution checking bit data.

[0039] The target error correction bit related data can be data related to the data bit of the error correction array data incorrectly read by the error correction module, which is determined by the error correction checking module according to the error correction array data and the to-be-checked solution checking bit data. For example, the target error correction bit related data can include but is not limited to the number of bits of the error correction array data incorrectly identified by the error correction module, the position of the error correction array data incorrectly identified by the error correction module in the error correction array data, and the number of bits of the error correction checking bit data incorrectly read by the error correction module. The number of bits of the error correction array data incorrectly identified by the error correction module can be one bit or multiple bits.

[0040] In the embodiment of the present application, after receiving the to-be-checked solution checking bit data sent by the error correction module, the error correction checking module can determine the target error correction bit related data causing the error correction module to incorrectly read the error correction array data according to the error correction array data and the to-be-checked solution checking bit data.

[0041] In S140, an error correction function checking result of the error correction module is determined according to the target error correction bit related data and the error correction position data.

[0042] The error correction function checking result can be used to reflect the detection result of the error correction function of the error correction module.

[0043] In the embodiment of the present application, the error correction checking module can determine whether the error correction function of the error correction module is normal according to the target error correction bit associated data and the error correction position data, to obtain an error correction function checking result of the error correction module. In the case that the error correction function of the error correction module is abnormal, the data transceiving function of the error correction module is interrupted, the error correction module is deactivated, and the error correction function checking result of the error correction module is sent to a central processor or other module capable of data processing and data analysis.

[0044] The technical scheme of the embodiment obtains error correction function checking data and error correction position data for checking the error correction function of the error correction module by the error correction checking module, and then sends the error correction function checking data to the error correction module, so that the error correction module generates to-be-checked solution checking bit data according to the error correction array data and the error correction checking bit data in the error correction function checking data. After the error correction checking module obtains the to-be-checked solution checking bit data, the target error correction bit associated data of the error correction array data can be determined according to the error correction array data and the to-be-checked solution checking bit data, and then the error correction function checking result of the error correction module can be determined according to the target error correction bit associated data and the error correction position data. Since the target error correction bit associated data can reflect the state of the potential error correction function of the error correction module, and the error correction position data can reflect the data position of the error data that can be identified when the error correction function of the error correction module is normal during the error correction function checking of the error correction module, the error correction checking module can accurately determine the abnormal state of the error correction function of the error correction module according to the target error correction bit associated data and the error correction position data, thereby ensuring the accuracy of the output data of the error correction module and solving the problems in the prior art that the fault of the error correction module cannot be found in time and the accuracy of the data transmission of the error correction module cannot be ensured due to the lack of error correction function detection of the error correction module. The fault of the error correction module can be found in time, and the accuracy of the data transmission of the error correction module can be ensured.

[0045] Embodiment Two

[0046] Figure 2 is a flowchart of an error correction module detection method provided in Embodiment Two of the present application. The embodiment is based on the above-mentioned embodiments and is embodied in the present embodiment. In the present embodiment, the error correction checking module obtains error correction function checking data and error correction position data for checking the error correction function of the error correction module, so that the error correction module generates to-be-checked solution checking bit data according to the error correction array data and the error correction checking bit data, and further determines the target error correction bit associated data of the error correction array data according to the error correction array data and the to-be-checked solution checking bit data, and determines the target error correction bit associated data of the error correction array data according to the error correction array data and the to-be-checked solution checking bit data. The specific optional implementation scheme is given. Accordingly, as shown in Figure 2 the method comprises the following operations:

[0047] S210, acquire error correction function verification data and error correction position data for verifying the error correction function of the error correction module.

[0048] In an optional embodiment of the present application, acquiring the error correction function verification data and the error correction position data for verifying the error correction function of the error correction module can include: acquiring original cache array data and standard check bit data in the memory; performing data bit inversion processing on the original cache array data to obtain error correction array data and error correction position data; and determining the standard check bit data as error correction check bit data.

[0049] The original cache array data can be data stored in the memory that needs to be checked, corrected, and forwarded by the error correction module. The standard check bit data can be check data calculated by the error correction module according to a check algorithm, used to verify the accuracy of the input data. The data bit inversion processing can be an operation of inverting one or more bits of data in a group of data.

[0050] In the embodiment of the present application, the error correction verification module can first determine the working state of the memory. If it is determined that the working state of the memory is an idle state, the original cache array data in the memory and the standard check bit data corresponding to the original cache array data can be further acquired. Then, the original cache array data can be subjected to data bit inversion processing according to the detection requirements of the error correction module to obtain error correction array data. The position data of the data bit subjected to the data bit inversion processing of the original cache array data can be taken as the error correction position data, and the standard check bit data corresponding to the original cache array can be taken as the error correction check bit data.

[0051] For example, when the memory is in a working state and the memory controller (a component for controlling the memory) needs to write data to the memory, the original cache array data A to be stored in the memory can be sent to the error correction module. The error correction module can perform encoding processing on the original cache array data A to obtain standard check bit data a. Then, the standard check bit data a and the original cache array data A can be sent to the memory, and the memory can store the standard check bit data a and the original cache array data A. When the error correction verification module verifies the error correction function of the error correction module (at this time, the memory is in an idle state), the error correction verification module can acquire the standard check bit data a and the original cache array data A from the memory. Then, a bit in the original cache array data A can be inverted to obtain error correction array data B. The standard check bit data a can be taken as the error correction check bit data, and the position data of the inverted data bit in the original cache array data A can be taken as the error correction position data.

[0052] In an optional embodiment of the present application, the error correction function check data and the error correction position data for checking the error correction function of the error correction module can include: obtaining the original array data, and performing data bit inversion processing on the original array data to obtain the original error correction array data and the error correction position data; sending the original array data to the error correction module to generate standard check bit data according to the original array data by the error correction module; determining the original error correction array data as the error correction array data, and determining the standard check bit data as the error correction check bit data.

[0053] The original array data can be data generated by the error correction check module autonomously or data obtained from a device other than the memory. The original error correction array data can be the result of data bit inversion processing on the original array data.

[0054] In the embodiment of the present application, the error correction check module can autonomously generate the original array data or obtain the original array data from other devices other than the memory. After obtaining the original array data, the error correction check module can further perform data bit inversion processing on the original array data to obtain the original error correction array data, and then take the position data of the data bits of the original array data subjected to the data bit inversion processing as the error correction position data, and send the original array data to the error correction module. After receiving the original array data, the error correction module can perform encoding calculation on the original array data based on the encoding function to determine the standard check bit data corresponding to the original array data, and then take the original error correction array data as the error correction array data, and determine the standard check bit data as the error correction check bit data.

[0055] For example, assuming that the original array data is a group of 32-bit data, from low bit to high bit, a1, a2, a3, a4, a5, a6, a7, a8, a9, a 10 , a 11 , a 12 , a 13 , a 14 , a 15 , a 16 , a 17 , a 18 , a 19 , a 20 , a 21 , a 22 , a 23 , a 24 , a 25 , a 26 , a 27 , a 28 , a 29 , a 30 , a 31 , a 32The error correction module can calculate the standard check bit data according to the following formula:

[0064] S220, send the error correction function check data to the error correction module, so as to generate the to-be-verified solution check bit data according to the error correction array data and the error correction check bit data through the error correction module.

[0065] Taking the calculation formula of the parity check bit data in the above standard as an example, the error correction module can calculate the to-be-checked solution parity check bit data according to the following formula:

[0066] E1 = a1 ^ a2 ^ a4 ^ a5 ^ a7 ^ a9 ^ a 11 ^ a 12 ^ a 14 ^ a 16 ^ a 18 ^ a 20 ^ a 22 ^ a 24 ^ a 26 ^ a 27 ^ a 29 ^ a 31 ^ p1

[0067] E2 = a1 ^ a3 ^ a4 ^ a6 ^ a7 ^ a 10 ^ a 11 ^ a 13 ^ a 14 ^ a 17 ^ a 18 ^ a 21 ^ a 22 ^ a 25 ^ a 26 ^ a 28 ^ a 29 ^ a 32 ^ p2

[0068] E3 = a2 ^ a3 ^ a4 ^ a8 ^ a9 ^ a 10 ^ a 11 ^ a 15 ^ a 16 ^ a 17 ^ a 18 ^ a 23 ^ a 24 ^ a 25 ^ a 26 ^ a 30 ^ a 31 ^ a 32 ^ p3

[0069] E4 = a5 ^ a6 ^ a7 ^ a8 ^ a9 ^ a 10 ^ a 11 ^ a 19 ^ a 20 ^ a 21 ^ a 22 ^ a 23 ^ a 24 ^ a 25 ^ a 26 ^ p4

[0070] E5 = a 12 ^ a13 ⊕a 14 ⊕a 15 ⊕a 16 ⊕a 17 ⊕a 18 ⊕a 19 ⊕a 20 ⊕a 21 ⊕a 22 ⊕a 23 ⊕a 24 ⊕a 25 ⊕a 26 ⊕p5

[0071] E6 = a 27 ⊕a 28 ⊕a 29 ⊕a 30 ⊕a 31 ⊕a 32 ⊕p6

[0072] E0=p1⊕p2⊕p3⊕p4⊕p5⊕p6⊕a1⊕a2⊕a3⊕a4⊕a5⊕a6⊕a7⊕a8⊕a9⊕a 10 ⊕a 11 ⊕a 12 ⊕a 13 ⊕a 14 ⊕a 15 ⊕a 16 ⊕a 17 ⊕a 18 ⊕a 19 ⊕a 20 ⊕a 21 ⊕a 22 ⊕a 23 ⊕a 24 ⊕a 25 ⊕a 26 ⊕a 27 ⊕a 28 ⊕a 29 ⊕a 30 ⊕a 31 ⊕a 32 ⊕p0

[0073] Wherein, E0 represents the 0th bit of the verification data to be verified, E1 represents the 1st bit of the verification data to be verified, E2 represents the 2nd bit of the verification data to be verified, E3 represents the 3rd bit of the verification data to be verified, E4 represents the 4th bit of the verification data to be verified, E5 represents the 5th bit of the verification data to be verified, and E6 represents the 6th bit of the verification data to be verified.

[0074] In an optional embodiment of the present application, the error correction module can be configured to determine the current check bit data according to the error correction check bit data, determine the target data bit of the error correction array data according to the current check bit data, and perform logical operation on the current check bit data and the target data bit data of the error correction array data to obtain the current solution check bit data of the to-be-checked solution check bit data.

[0075] In the formula, the current check bit data can be at least one bit of the error correction check bit data, and is used to calculate a bit of the to-be-checked solution check bit data. The target data bit can be at least one data bit of the error correction array data corresponding to the current check bit data. The target data bit data can be data of the target data bit of the error correction array data. The current solution check bit data can be a bit of the to-be-checked solution check bit data, which is obtained by the error correction module according to the current check bit data and the target data bit data.

[0076] In the embodiment of the present application, after obtaining the error correction check bit data, the error correction module can further obtain the current check bit data from the error correction check bit data, and then determine the target data bit of the error correction array data corresponding to the current check bit data according to the current check bit data. After obtaining the target data bit of the error correction array data, the error correction module can determine the target data bit data of the error correction array data according to the target data bit of the error correction array data, and then perform logical operation on the current check bit data and the target data bit data of the error correction array data to obtain the current solution check bit data of the to-be-checked solution check bit data.

[0077] For example, assuming that the current check bit data is p6, the target data bits of the error correction array data are data bit 27, data bit 28, data bit 29, data bit 30, data bit 31 and data bit 32, and the target data bit data are a 27 , a 28 , a 29 , a 30 , a 31 and a 32 , and then E6 is calculated according to E6=a 27 ⊕a 28 ⊕a 29 ⊕a 30 ⊕a 31 ⊕a 32 ⊕p6, and the calculation result of E6 is taken as the current solution check bit data, i.e., the 6th bit of the to-be-checked solution check bit data.

[0078] S230, determining the reference solution check bit data and the combined solution check bit data according to the to-be-checked solution check bit data.

[0079] The reference solution check bit data can be used to represent one data bit in the to-be-checked solution check bit data, and the corresponding numerical value is obtained by logical operation of the error correction module according to all data of the error correction array data and all data of the error correction check bit data. The combined solution check bit data can be used to represent other data bits in the to-be-checked solution check bit data except the data bit corresponding to the reference solution check bit data. The calculation of each bit of the combined solution check bit data is performed by the error correction module according to part of the error correction array data and part of the error correction check bit data.

[0080] In the embodiment of the application, after obtaining the to-be-checked solution check bit data, the error correction check module can divide the to-be-checked solution check bit data to obtain the reference solution check bit data and the combined solution check bit data.

[0081] For example, it is assumed that the to-be-checked solution check bit data is E6, E5, E4, E3, E2, E1 and E0 from high bit to low bit. The reference solution check bit data can be E0, and the combined solution check bit data can be E6, E5, E4, E3, E2 and E1.

[0082] S240, determining a reference value of the reference solution check bit data and a combined value of the combined solution check bit data.

[0083] The reference value of the reference solution check bit data can be the data corresponding to the reference solution check bit data in the to-be-checked solution check bit data. The combined value of the combined solution check bit data can be the data corresponding to the combined solution check bit data in the to-be-checked solution check bit data.

[0084] In the embodiment of the application, the error correction check module can determine the reference value of the reference solution check bit data according to the reference solution check bit data and the to-be-checked solution check bit data, and determine the combined value of the combined solution check bit data according to the combined solution check bit data and the to-be-checked solution check bit data.

[0085] For example, it is assumed that the to-be-checked solution check bit data is 1110, the reference solution check bit data is used to represent the 0th bit of the to-be-checked solution check bit data, and the combined solution check bit data is used to represent the 3rd bit to the 1st bit of the to-be-checked solution check bit data, then the reference value of the reference solution check bit data is 0, and the combined value of the combined solution check bit data is 111.

[0086] S250, determining the target error correction bit related data of the error correction array data according to the reference value of the reference solution check bit data and the combined value of the combined solution check bit data.

[0087] In the embodiment of the application, the error correction check module can determine the target error correction bit related data of the error correction array data according to the reference value of the reference solution check bit data and the combined value of the combined solution check bit data.

[0088] In an optional embodiment of the present application, the target error bit related data can include error bit data and data position of the error bit data; and determining the target error bit related data of the error correction array data according to the reference value of the reference solution check bit data and the combined value of the combined solution check bit data can include: determining the error bit data and the data position of the error bit data as null when the reference value of the reference solution check bit data is a first reference value and the combined value of the combined solution check bit data is a first combined value; determining the number of the error bit data as a first number when the reference value of the reference solution check bit data is a second reference value and the combined value of the combined solution check bit data is the first combined value; comparing the error correction function check data and the to-be-checked solution check bit data according to the same data bit comparison rule, and determining the data position of the error correction function check data different from the to-be-checked solution check bit data as the data position of the error bit data; determining the number of the error bit data as a second number and the data position of the error bit data being located in the error correction array data and / or the error correction function check data when the reference value of the reference solution check bit data is the first reference value and the combined value of the combined solution check bit data is a second combined value; determining the number of the error bit data of the error correction module as the first number when the reference value of the reference solution check bit data is the second reference value and the combined value of the combined solution check bit data is the second combined value; performing target radix conversion on the combined value of the combined solution check bit data to obtain target radix error bit data; and determining the data position of the error bit data according to the target radix error bit data.

[0089] The error bit data can be used to represent the bits of the data read incorrectly by the error correction module when reading the error correction array data. The data position of the error bit data can be the position of the data read incorrectly. The first reference value and the second reference value can be two different reference values of the reference syndrome data. For example, the first reference value can be 0 and the second reference value can be 1. The first combination value can represent a combination of the syndrome data in which all the combination values are 0. The second combination value can be any possible combination of the syndrome data in which not all the combination values are 0. For example, if the first combination value is 00, the second combination value can be any one of 01, 10 and 11. The target base conversion can be a data conversion of the combination values of the syndrome data into a target base. The target base can be any desired base, for example, the target base conversion can be a decimal conversion. The same data bit comparison rule can be a rule for comparing two bits of the same data according to the data bits. For example, the two bits of the same data can be compared in order from low to high, or in order from high to low. The specific comparison order of the same data bit comparison rule is not limited in the embodiments of the present application. The target base error bit data can be the data conversion result of the combination values of the syndrome data converted into the target base. The first number can be number 1 and the second number can be number 2.

[0090] In the embodiment of the present application, when the error correction check module determines that the reference value of the reference check bit data is the first reference value and the combined value of the combined check bit data is the first combined value, it can be further determined that the data position of the error check bit data and the error bit data is empty, that is, the error correction module is normal. When the error correction check module determines that the reference value of the reference check bit data is the second reference value and the combined value of the combined check bit data is the first combined value, it can be further determined that the number of error bit data is the first number, and the error correction check bit data is abnormal. At this time, the same data bit comparison rule can be determined according to the data recognition requirement, and then the error correction function check data and the to-be-checked check bit data are compared according to the same data bit comparison rule, and then the data position of the error correction function check data different from the to-be-checked check bit data is taken as the data position of the error bit data. When the error correction check module determines that the reference value of the reference check bit data is the first reference value and the combined value of the combined check bit data is the second combined value, it can be further determined that the number of error bit data is the second number, and it can be determined that the data position of the error bit data is located in the error correction array data and / or the error correction function check data, that is, there are two error data in the error correction array data and / or the error correction function check data read by the error correction module. When the error correction check module determines that the reference value of the reference check bit data is the second reference value and the combined value of the combined check bit data is the second combined value, it can be further determined that the number of error bit data of the error correction module is the first number, and then the combined value of the combined check bit data is converted into a target radix to obtain target radix error bit data, so that the target radix error bit data is taken as the data bit number corresponding to the data position of the error bit data, and then the data position of the error bit data is determined.

[0091] S260, determining the error correction function check result of the error correction module according to the target error correction bit associated data and the error correction position data.

[0092] In an optional embodiment of the present application, when it is determined that the data position of the error correction position data is the first number, the error correction function check result of the error correction module can be determined according to the target error correction bit associated data and the error correction position data, which can include: when it is determined that the number of error bit data is the first number and the data position of the error bit data is the same as the error correction position data, it is determined that the error correction function of the error correction module is normal; when it is determined that the number of error bit data is the first number and the data position of the error bit data is located in the error correction function check data, the number of error bit data is the first number and the data position of the error bit data is different from the error correction position data, the number of error bit data is the second number, or the number of error bit data is empty, it is determined that the error correction function of the error correction module is abnormal, and the error correction function check result is sent to the target data processing module.

[0093] The target data processing module can be a module capable of data analysis and processing, and is configured to record the error correction function verification result of the error correction module. For example, the target data processing module can include a central processing unit.

[0094] In the embodiment of the present application, when the data position of the error correction position data is the first quantity, the error correction verification module determines that the error correction function of the error correction module is normal when the number of error bit data is the first quantity and the data position of the error bit data is the same as the error correction position data, and sends the data of the normal error correction module function to the target data processing module. The error correction verification module determines that the error correction function of the error correction module is abnormal when any of the following conditions is met, and sends the error correction function verification result to the target data processing module. The first condition is that the number of error bit data is the first quantity and the data position of the error bit data is one bit in the error correction function verification data, the second condition is that the number of error bit data is the second quantity, the third condition is that the number of error bit data is empty, and the fourth condition is that the number of error bit data is the first quantity and the data position of the error bit data is different from the error correction position data.

[0095] When the data position of the error correction position data is the second quantity, the error correction function verification result of the error correction module is determined according to the target error bit associated data and the error correction position data, which can include: when the number of error bit data is the second quantity and the data position of the error bit data is the same as the error correction position data, it is determined that the error correction function of the error correction module is normal; when the number of error bit data is the second quantity and the data position of the error bit data is different from the error correction position data, or the number of error bit data is the first quantity or empty, it is determined that the error correction function of the error correction module is abnormal, and the error correction function verification result is sent to the target data processing module.

[0096] At present, in chip design, the memory on the chip mainly uses ECC (Error Correcting Code) module to ensure the accuracy of the data read from the memory. In production or long-term use, if the function of the ECC module is defective, even if the data read from the memory is inconsistent with the data written into the memory, it will not be checked out, and the chip will consider that the data read from the memory is correct, thereby causing the chip function error. When the ECC module does not have a self-detection module, even if the ECC function is wrong, it cannot be perceived by the chip system in time, and measures cannot be taken in time when the data read from the memory is inconsistent with the data written into the memory. The error correction verification module of the present application can verify the ECC module, discover the abnormal function of the ECC module in time, avoid the serious error behavior of the chip caused by the abnormal ECC module, and ensure the safe transmission of the data of the memory.

[0097] Figure 3is a schematic diagram of a self-correcting system provided by embodiment two of the present application, in a specific example, the self-correcting system comprises a CPU (Central Processing Unit), a memory, a memory control subsystem, a bus interaction module and a function module, wherein: the CPU can be used to initiate read-write function modules and operations of the memory, and can also perform interrupt processing, etc. The function module can be a general module with certain functions, in addition to having corresponding module functions (such as an Ethernet interface), it can also store data. The memory can be used to store data. The memory control subsystem can be used to check data sent by the memory to the CPU and the function module, control the read-write timing of the memory, and also has ECC (Error Correcting Code) and EIM (Error Inject Module) functions. The bus interaction module is used for data interaction between the CPU, the function module and the memory control subsystem.

[0098] Figure 4 is a data transmission schematic diagram of a self-correcting system provided by embodiment two of the present application, as Figure 4As shown, the self-correction system comprises an ECC encoding module, an ECC decoding module, a CPU, a memory, an EIM module, an I / O module and a memory controller, wherein the ECC encoding module and the ECC decoding module correspond to the error correction module, the memory controller and the EIM module jointly constitute the error correction and check module, and the target data processing module can be the CPU. The I / O module corresponds to a functional module and is used to forward the data of the memory controller to the peripheral device. The memory controller can be used for conversion of bus signal to memory read / write timing, generation of read enable signal, write enable signal and chip select enable signal, and sending of the read enable signal, the write enable signal and the chip select enable signal to the memory. The ECC encoding module can perform ECC encoding on 32-bit data required by the memory controller to be written into the memory to generate 7-bit standard check bit data, and then send the 32-bit data and the standard check bit data to the memory. When the memory is in an idle state, the EIM module can perform error correction function detection on the ECC decoding module. The EIM module can first read original cache array data, take inversion of a certain bit of the original cache array data to obtain error correction array data and error correction position data, take the standard check bit data as error correction check bit data, and then send the error correction position data to the memory controller. At this time, the chip selection module (corresponding to the module connected with rdata[0:30] and rdata_m[0:31]) can select the EIM module, and transmit the error correction array data obtained by the EIM module to the ECC decoding module, and the memory sends the error correction check bit data to the ECC decoding module. The ECC decoding module receives the error correction array data in the order of low-to-high data bit through rdata[0] to rdata

[31] , and then determines to-be-checked check bit data according to the error correction array data and the error correction check bit data, and sends the error correction array data of rdata[0] to rdata

[31] and the to-be-checked check bit data to the memory controller. The memory controller can determine error bit data of the ECC decoding module reading the error correction array data and data position of the error bit data according to the to-be-checked check bit data and the error correction array data, and record the data position of the error bit data. If the data position of the inversion data in the original cache array data is the same as the data position of the error bit data parsed by the memory controller, it indicates that the ECC decoding module function is normal, the ecc_ok pin is set to 1, and the data of the ECC decoding module function normal is reported to the CPU. If the error bit data is 1 bit, it indicates that the ECC decoding module error correction function is abnormal, and there is 1-bit reading abnormality (at this time, the data position of the error bit data is different from the data position of the inversion data in the original cache array data, or the data position of the error bit data is located in one bit of the error correction function check data), and the data position of the error bit data is reported to the CPU.If the error bit data is 2 bits, it indicates that the ECC decoding module has an abnormal error correction function, and there is a 2-bit read error. The memory controller sends the data position of the error bit data to the CPU. When the memory is in the working state, the ECC decoding module reads data from the memory, and the rdata_m[0] to rdata_m

[31] of the memory can send the data required by the ECC decoding module to the rdata[0] to rdata

[31] of the ECC decoding module in the order of data bit 0 to data bit 31. The ECC decoding module can send the data of rdata[0] to rdata

[31] to the memory controller, and also generate the uncheck bit data (used to check the data received by rdata[0] to rdata

[31] ) according to the data of rdata[0] to rdata

[31] .

[0099] After obtaining the uncheck bit data, the ECC decoding module can determine whether the memory has a data read error according to the uncheck bit data. If the ECC decoding module finds that the memory has a 1-bit data read error, the ECC decoding module performs automatic correction, sends the correct data to the memory controller, and sends the correct data to the I / O module and / or the CPU by the memory controller. If the ECC decoding module finds that the memory has a 2-bit data read error, the ECC decoding module sets the ecc_det pin to 1 to send a signal to the I / O module through the ecc_det pin to make the state of the I / O module pin safe. At the same time, an interrupt is generated to inform the CPU that there is a 2-bit error in the memory read. The CPU configures the chip to a safe state, and the I / O module releases the control of the I / O pin state when the CPU configures the chip to the safe state.

[0100] The technical scheme of the embodiment is characterized in that the error correction checking module obtains error correction function checking data and error correction position data for checking the error correction function of the error correction module, and then sends the error correction function checking data to the error correction module, so that the error correction module generates to-be-checked solution check bit data according to the error correction array data and the error correction check bit data in the error correction function checking data. After the error correction checking module obtains the to-be-checked solution check bit data, the target error correction bit correlation data of the error correction array data can be determined according to the error correction array data and the to-be-checked solution check bit data, and then the error correction function checking result of the error correction module can be determined according to the target error correction bit correlation data and the error correction position data. Since the target error correction bit correlation data can reflect the state of the potential error correction function of the error correction module, and the error correction position data can reflect the data position of the error data that can be identified when the error correction function of the error correction module is checked and the function of the error correction module is normal, the error correction checking module can accurately determine the abnormal state of the error correction function of the error correction module according to the target error correction bit correlation data and the error correction position data, thereby ensuring the accuracy of the output data of the error correction module, solving the problem that the fault of the error correction module cannot be found in time and the accuracy of the data transmission of the error correction module cannot be ensured due to the lack of error correction function detection of the error correction module, and the fault of the error correction module can be found in time and the accuracy of the data transmission of the error correction module can be ensured. It should be noted that any arrangement and combination of the technical features in the above embodiments also belong to the protection scope of the present application.
