Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of data storage, and in particular, to a data processing method, device, and electronic device. Background Art

[0002] When electronic devices store data in memory, the reliability of the data can be ensured through error checking and correction (ECC) technology.

[0003] At present, electronic devices can protect the impact of memory particle errors on data through ECC data. For example, the memory can obtain the ECC data corresponding to the data and store the ECC data in an additional memory. When the electronic device reads the data, the memory can generate new ECC data based on the data, and verify it through the new ECC data and the ECC data stored in the additional memory. If the ECC data is different, it means that an error occurred when the data was stored in the memory. However, according to the above method, the electronic device can only identify the situation where the data is wrong when the memory particle fails, but cannot identify the situation where the data is wrong during the link transmission process, which leads to low accuracy of data verification.

[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0047] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0048] To facilitate understanding, the concepts involved in the embodiments of the present disclosure are first described.

[0049] Electronic device: a device with wireless transceiver function. Electronic devices can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; they can also be deployed on the water (such as ships, etc.). The electronic device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, a wireless terminal in industrial control, a vehicle-mounted electronic device, a wireless terminal in self-driving, a wireless electronic device in remote medical, a wireless electronic device in smart grid, a wireless electronic device in transportation safety, a wireless electronic device in smart city, a wireless electronic device in smart home, a wearable electronic device, etc. The electronic device involved in the embodiments of the present disclosure can also be called a terminal, a user equipment (UE), an access electronic device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote electronic device, a mobile device, a UE electronic device, a wireless communication device, a UE agent or a UE device, etc. Electronic devices may also be fixed or mobile.

[0050] In the related art, electronic devices can verify the data stored in the memory through the ECC technology to avoid data errors during the storage process. At present, electronic devices can identify data errors caused by memory hardware problems. For example, when the memory generates ECC data corresponding to the data, the ECC data can be stored separately in other storage devices. When the electronic device reads the data, the memory can generate the ECC data corresponding to the data again, and then compare the two ECC data. If the ECC data is different, it means that there is a problem with the data during storage in the memory device, and then the business using the data is stopped. However, by additionally saving ECC data, only the situation where the data is caused by memory hardware failure can be identified, and the situation where the data is wrong during the link transmission process cannot be identified. For example, if the data is wrong during the transmission process, the two ECCs generated by the memory device are also the same, which results in low accuracy of data verification.

[0051] In order to solve the technical problem of low accuracy of data verification in the related art, the embodiment of the present disclosure provides a data processing method, wherein an electronic device obtains first data and a first error correction code in a storage device, wherein the first error correction code is an error correction code generated when the storage device stores the first data, the electronic device generates a second error correction code according to the first data, and the electronic device verifies the first data according to the first error correction code and the second error correction code to obtain a first verification result, if the first verification result is that the first data verification fails, the electronic device performs error correction processing on the first data or generates an interrupt signal corresponding to the first data, if the first verification result is that the first data verification passes, the electronic device performs business processing according to the first data. In this way, if an error occurs in the first data, the electronic device can timely correct the first data or generate an interrupt signal for the first data, thereby improving the reliability of the first data, and since the first error correction code is an error correction code generated when the storage device stores the first data, and the second error correction code is an error correction code generated when the electronic device obtains the first data from the memory device, therefore, the first error correction code and the second error correction code can be used to identify problems in the first data transmission process and problems in the first data storage process in the storage device, thereby improving the accuracy of data verification.

[0052] Next, combine Figure 1 , the application scenarios of the embodiments of the present disclosure are described.

[0053] Figure 1 A schematic diagram of an application scenario provided by an embodiment of the present disclosure. Figure 1, including: an electronic device. Among them, the electronic device includes a memory and a system on chip. The memory includes 128 bits of data and a first error correction code, wherein the first error correction code is an error correction code generated according to the 128 bits of data when the memory obtains the 128 bits of data. The system on chip receives the 128 bits of data and the first error correction code sent by the memory, and generates a second error correction code according to the 128 bits of data. The system on chip determines that the 128 bits of data are correct according to the first error correction code and the second error correction code, and the electronic device performs business processing according to the 128 bits of data. In the above method, since the first error correction code is an error correction code generated when the storage device stores the first data, and the second error correction code is an error correction code generated when the electronic device obtains the first data from the memory device, therefore, the first error correction code and the second error correction code can be used to determine that there is no error in the 128 bits of data during storage and transmission, thereby improving the accuracy of data verification and data reliability.

[0054] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0055] Figure 2 A flowchart of a data processing method provided by an embodiment of the present disclosure. Figure 2 , the method may include:

[0056] S201: An electronic device obtains first data and a first error correction code from a storage device.

[0057] The execution subject of the embodiment of the present disclosure may be an electronic device, or a data processing device disposed in the electronic device. The data processing device may be implemented by software, or the data processing device may be implemented by a combination of software and hardware.

[0058] Optionally, the electronic device can obtain the first data in the memory of the electronic device through a system on chip (System on Chip, SOC). Optionally, the first data is business data pre-stored in the memory of the electronic device. For example, a user uses an electronic device to log in to a business system and modifies user data in the business system, then the modified user data can be the first data, and the electronic device can store the modified user data in the memory. For example, the memory device can be a 5th generation low power double data rate memory (Low Power Double Data Rate SDRAM 5, LPDDR5). Optionally, the storage device can be a storage device inside the electronic device, or it can be a storage device outside the electronic device, which is not limited in the embodiments of the present disclosure.

[0059] Optionally, the first error correction code is used to correct errors in the first data. For example, the first error correction code may be ECC data corresponding to the first data, and the electronic device may determine whether the first data is erroneous through the ECC data. Optionally, the first error correction code is an error correction code generated when the storage device stores the first data. For example, when the SOC stores the first data in the memory, if the memory receives the first data, the memory generates ECC data corresponding to the first data based on the first data, and stores the first data and the ECC data corresponding to the first data.

[0060] Optionally, when the electronic device receives a data acquisition request corresponding to the first data, the electronic device can acquire the first data and the first error correction code from the storage device. For example, the data acquisition request may include an identifier of the data to be acquired. When the electronic device receives the data acquisition request, the electronic device can determine the data that the SOC needs to read according to the identifier of the data to be acquired. When the SOC reads the data from the memory, the memory can send the data and the ECC data corresponding to the data to the SOC in the electronic device.

[0061] Next, combine Figure 3 , a process of an electronic device obtaining first data and a first error correction code in a storage device is described.

[0062] Figure 3 A schematic diagram of obtaining first data and a first error correction code provided by an embodiment of the present disclosure. Figure 3 , including an electronic device. The electronic device includes a system on chip SOC and a memory. When the electronic device receives a request to obtain first data, the system on chip SOC can send a request message for the first data to the memory, and the memory sends the first data and a first error correction code corresponding to the first data to the SOC according to the request message for the first data.

[0063] S202: The electronic device generates a second error correction code according to the first data.

[0064] Optionally, the second error correction code is used to correct errors in the first data. For example, the second error correction code may be ECC data corresponding to the first data, and the electronic device may determine whether the first data is erroneous through the ECC data. Optionally, the second error correction code is an error correction code generated by the electronic device based on the first data after the electronic device obtains the first data from the storage device. For example, the memory may send the first data and the first error correction code corresponding to the first data generated when the memory stores the first data to the electronic device, and when the electronic device receives the first data and the first error correction code sent by the memory, the second error correction code is generated based on the first data.

[0065] S203: The electronic device verifies the first data according to the first error correction code and the second error correction code to obtain a first verification result.

[0066] Optionally, the first verification result is used to indicate whether the first data obtained by the electronic device from the memory device is erroneous. For example, if the first verification result is that the first data verification is passed, it means that there is no error in the first data during storage and / or transmission; if the first verification result is that the first data verification is not passed, it means that there is an error in the first data during storage and / or transmission.

[0067] Optionally, the first data may be verified according to the following feasible implementation method to obtain a first verification result: the electronic device obtains a first matching degree between the first error correction code and the second error correction code. Optionally, the first matching degree is used to indicate the similarity between the first error correction code and the second error correction code. For example, the bit width of the first error correction code and the second error correction code may be 8 bits, and the first matching degree of the first error correction code and the second error correction code is obtained by performing a bitwise exclusive OR operation on the first error correction code and the second error correction code.

[0068] The electronic device obtains a first verification result based on the first matching degree. Optionally, if the first matching degree is greater than or equal to the first threshold value, the electronic device determines that the first verification result is that the first data verification is passed. For example, if the data of each bit of the first error correction code and the second error correction code are the same, the electronic device determines that the first verification result between the first error correction code and the second error correction code is that the first data verification is passed. For example, if the first error correction code and the second error correction code are the same, it means that there is no error in the first data during storage or transmission, and the electronic device can use the first data for business processing.

[0069] Optionally, if the first matching degree is less than the first threshold, the electronic device determines that the first verification result is that the first data verification fails. For example, if after the bitwise XOR operation of the first error correction code and the second error correction code, the operation result is flipped by 1 bit compared with the preset result (the bitwise XOR operation result when the first error correction code and the second error correction code are exactly the same), it is determined that the first matching degree is less than the first threshold, and the electronic device determines that the first verification result between the first error correction code and the second error correction code is that the first data verification fails. In this way, the electronic device can accurately determine whether the first data is wrong through the first error correction code and the second error correction code, thereby improving the reliability of the data.

[0070] S204: The electronic device processes the first data according to the first verification result.

[0071] Optionally, the electronic device processes the first data according to the first verification result, and there are two situations as follows:

[0072] Case 1: The first verification result is that the first data verification passes.

[0073] Optionally, if the first verification result is that the first data verification is passed, the electronic device performs business processing according to the first data. For example, when the electronic device receives a page display request, the electronic device can obtain page data corresponding to the page in the memory. If the first verification result is that the page data verification is passed, it means that there is no error in the page data during storage or transmission, and the electronic device can display the corresponding page according to the page data.

[0074] Case 2: The first verification result is that the first data verification fails.

[0075] Optionally, if the first verification result is that the first data verification fails, the electronic device performs error correction processing on the first data or generates an interrupt signal corresponding to the first data. Optionally, the interrupt signal is used to instruct the electronic device to stop using the first data. For example, when a page display request is received in an electronic device, the electronic device can obtain the page data corresponding to the page in the memory. If the first verification result is that the page data verification fails, it means that the page data is wrong during the storage or transmission process. If the electronic device can correct the page data, the electronic device displays the corresponding page according to the page data after error correction. If the electronic device cannot correct the page data, the electronic device generates an interrupt signal corresponding to the page data, and stops displaying the page corresponding to the page data through the interrupt signal.

[0076] Optionally, the first data may be error corrected according to the following feasible implementation method: the bit width of the data that is different between the first error correction code and the second error correction code is obtained, and when the bit width is less than or equal to a preset threshold, the first data is error corrected. For example, if there is a 1-bit difference in data between the first error correction code and the second error correction code, the electronic device may perform error correction on the first data (e.g., the first error correction code and the second error correction code are both ECC data, and the electronic device may determine the location of the error in the first data through the parity check bit in the ECC data, and then correct the first data).

[0077] Optionally, an interrupt signal corresponding to the first data may be generated according to the following feasible implementation method: the bit width of the data that is different between the first error correction code and the second error correction code is obtained, and when the bit width is greater than a preset threshold, an interrupt signal corresponding to the first data is generated. For example, if there is a 2-bit difference in data between the first error correction code and the second error correction code, the electronic device cannot perform error correction processing on the first data, and the electronic device may generate an interrupt signal (an interrupt signal may be generated for the SOC or an interrupt signal may be generated for the memory) to stop using the first data.

[0078] The disclosed embodiment provides a data processing method, wherein an electronic device obtains first data and a first error correction code from a storage device, generates a second error correction code based on the first data, verifies the first data based on the first error correction code and the second error correction code, and obtains a first verification result. If the first verification result is that the first data verification fails, the electronic device performs error correction processing on the first data or generates an interrupt signal corresponding to the first data. If the first verification result is that the first data verification passes, the electronic device performs service processing based on the first data. In this way, the electronic device can accurately determine whether the first data is wrong through the first error correction code and the second error correction code, and can correct the first data when the first data is wrong, thereby improving the reliability of the first data. Moreover, since the first error correction code is an error correction code generated when the storage device stores the first data, and the second error correction code is an error correction code generated when the electronic device obtains the first data from the memory device, the first error correction code and the second error correction code can be used to identify problems that occur during the transmission of the first data and problems that occur during the storage of the first data in the storage device, thereby improving the accuracy of data verification.

[0079] exist Figure 2 Based on the embodiment shown in the figure, before the electronic device obtains the first data and the first error correction code in the storage device, the electronic device may also send the first data to the storage device. Figure 4 , a process of sending first data from an electronic device to a memory device is described.

[0080] Figure 4 A schematic diagram of a method for sending first data to a storage device provided by an embodiment of the present disclosure. Figure 4 The method flow includes:

[0081] S401: An electronic device obtains first data, and generates a third error correction code according to the first data.

[0082] Optionally, the third error correction code is used to correct errors in the first data. For example, the third error correction code may be ECC data corresponding to the first data, and the electronic device may determine whether the first data is erroneous through the ECC data. Optionally, the third error correction code is an error correction code generated when the electronic device obtains the first data. For example, when the electronic device needs to write data, the electronic device may obtain the third error correction code of the data.

[0083] S402: The electronic device sends the first data and the third error correction code to the storage device, so that the storage device verifies the first data according to the third error correction code.

[0084] Optionally, the first data and the third error correction code may be sent to the storage device in the following feasible implementation manner: the electronic device obtains the first clock cycle required for the electronic device to send the first data to the storage device. For example, it takes 16 clock cycles for the electronic device to send the first data to the storage device. The electronic device obtains the second clock cycle required for the electronic device to send the third error correction code to the storage device. For example, if it takes 16 clock cycles for the electronic device to send the first data to the storage device, and it takes another 1 clock cycle to send the ECC data to the storage device, then the first clock cycle is 16 clock cycles, and the second clock cycle is 1 clock cycle.

[0085] The electronic device determines the sum of the first clock cycle and the second clock cycle as the transmission cycle for the electronic device to send data to the storage device once. For example, when the SOC reads data from the memory or writes data to the memory, the cycle required to send data once is the transmission cycle. For example, if the first clock cycle is 16 clock cycles and the second clock cycle is 1 clock cycle, the transmission cycle for the electronic device to send data to the storage device once is 17 clock cycles, that is, the minimum granularity of the electronic device to transmit to the memory device is the data sent in 17 clock cycles. In this way, the waste of bandwidth can be avoided (for example, if the first data occupies a transmission cycle, an ECC data needs to be sent in the next transmission cycle. Since the ECC data is small, the data sent in other clock cycles in the transmission cycle is empty, resulting in a waste of bandwidth). The electronic device can send the first data and the third error correction code to the memory device in one transmission cycle, thereby improving the efficiency of data transmission and the flexibility of data transmission.

[0086] Optionally, ecc data can be sent by adding ecc signal lines. For example, if the minimum granularity of a read or write operation performed by the SOC in the memory is 16 beats of business data, then there are 8 signal lines for data transmission, and an additional data transmission signal line can be added to send ecc data. Therefore, through 9 data transmission signal lines, the first data and the third error correction code can be sent in one transmission process (8 signal lines send the first data, and 1 signal line sends the third error correction code).

[0087] Next, combine Figure 5A-Figure 5B , the process of sending the first data and the third error correction code is explained.

[0088] Figure 5A A schematic diagram of sending first data and a third error correction code provided by an embodiment of the present disclosure. Figure 5A, including 17 clock cycles. Among them, the minimum granularity of each data transmission by the electronic device and the memory is 17 clock cycles. Clock cycle 1, clock cycle 2, ..., clock cycle 16 are used to send the first data, and clock cycle 17 is used to send the third error correction code. In this way, the first data and the third error correction code can be sent in a minimum granularity, thereby saving bandwidth and improving the efficiency of data transmission.

[0089] Figure 5B Another schematic diagram of sending first data and third error correction code provided by the embodiment of the present disclosure. Figure 5B , including 9 signal lines. Among them, the electronic device and the memory transmit data at a minimum granularity of 9 signal lines each time. Signal line 1, signal line 2, ..., signal line 8 are used to send 16 beats of the first data, and signal line 9 is used to send 8 beats of the third error correction code. In this way, the first data and the third error correction code can be sent in a minimum granularity, thereby saving bandwidth and improving the efficiency of data transmission.

[0090] Optionally, when the storage device receives the first data and the third error correction code, the first data can be verified by the third error correction code. For example, when the storage device receives the first data and the ECC data corresponding to the first data, the ECC data can be used to verify whether the first data is erroneous during the transmission process, thereby improving the reliability of the first data.

[0091] The disclosed embodiment provides a method for sending first data to a storage device, wherein the electronic device obtains the first data and generates a third error correction code according to the first data, the electronic device obtains a first clock cycle required for the electronic device to send the first data to the storage device, and a second clock cycle required for the electronic device to send the third error correction code to the storage device, the electronic device determines the sum of the first clock cycle and the second clock cycle as a sending cycle for the electronic device to send data to the storage device once, and sends the first data and the third error correction code to the storage device through the sending cycle. In this way, the electronic device can send the first data and the third error correction code to the memory device in one data sending cycle, thereby avoiding bandwidth waste and improving the efficiency and flexibility of data sending.

[0092] Based on any of the above embodiments, the present disclosure also includes another data processing method. Figure 6 , the process of another data processing method is explained.

[0093] Figure 6 A flowchart of another data processing method provided by an embodiment of the present disclosure. Figure 6 The method flow includes:

[0094] S601: A storage device receives first data and a third error correction code sent by an electronic device.

[0095] Optionally, the storage device may receive the first data and the third error correction code sent by the electronic device, wherein the third error correction code is an error correction code generated by the electronic device based on the first data. For example, when the electronic device obtains the first data, it generates ECC data based on the first data and sends the first data and the ECC data to the storage device.

[0096] S602: The storage device generates a first error correction code according to the first data.

[0097] Optionally, when the storage device receives the first data and the third error correction code sent by the electronic device, the storage device may generate the first error correction code according to the first data. For example, when the storage device receives the first data sent by the electronic device and the ECC data corresponding to the first data, it may generate new ECC data according to the first data, and verify the first data according to the ECC data generated by the electronic device and the ECC data generated by the storage device.

[0098] S603: The storage device verifies the first data according to the first error correction code and the third error correction code to obtain a second verification result.

[0099] Optionally, the second verification result is used to indicate whether the first data received by the memory device is erroneous. For example, if the second verification result is that the first data is verified successfully, it means that there is no error in the first data during transmission; if the second verification result is that the first data is not verified successfully, it means that there is an error in the first data during transmission.

[0100] Optionally, the first data may be verified according to the following feasible implementation method to obtain a first verification result: the storage device obtains a second matching degree between the first error correction code and the third error correction code. Optionally, the second matching degree is used to indicate the similarity between the first error correction code and the third error correction code. For example, the bit width of the first error correction code and the third error correction code may be 8 bits, and the second matching degree of the first error correction code and the third error correction code is obtained by comparing each bit of the first error correction code and the third error correction code. For example, the second matching degree may be determined by a bitwise XOR operation between the first error correction code and the third error correction code.

[0101] The storage device obtains a second verification result based on the second matching degree. Optionally, if the second matching degree is greater than or equal to the second threshold value, the storage device determines that the second verification result is that the first data verification is passed. For example, if the data of each bit of the first error correction code and the third error correction code are the same, the storage device determines that the second verification result between the first error correction code and the third error correction code is that the first data verification is passed. For example, if the first error correction code and the third error correction code are the same, it means that there is no error in the first data during the transmission process, and the storage device can store the first data.

[0102] Optionally, if the second matching degree is less than the second threshold, the storage device determines that the second verification result is that the first data verification fails. For example, if there is one bit of data difference between the first error correction code and the third error correction code, the electronic device determines that the second verification result between the first error correction code and the third error correction code is that the first data verification fails. For example, if there are multiple bits of data difference between the first error correction code and the third error correction code, it means that the first data is wrong during the transmission process, and the storage device can perform error correction processing on the first data.

[0103] S604: The storage device processes the first data and the first error correction code according to the second verification result.

[0104] Optionally, the storage device processes the first data according to the second verification result, and there are two situations as follows:

[0105] Case 1: The second verification result is that the first data verification passed.

[0106] Optionally, if the second verification result is that the first data verification is passed, the storage device stores the first data and the first error correction code. For example, when the storage device receives the page data sent by the electronic device and the third error correction code corresponding to the page data, the first error correction code corresponding to the page data can be generated, and the page data can be verified by the first error correction code and the third error correction code. If the verification result is that the page data verification is passed, it means that the electronic device has no error in the process of sending the page data. Therefore, the memory data can store the page data and the first error correction code corresponding to the page data.

[0107] Case 2: The second verification result is that the first data verification fails.

[0108] Optionally, if the second verification result is that the first data verification fails, the storage device performs error correction processing on the first data or generates an interrupt signal corresponding to the first data. Optionally, the interrupt signal is used to instruct the electronic device to stop using the first data. For example, if the second verification result is that the first data verification fails, it means that an error occurs in the process of the electronic device sending the first data to the storage device. If the storage device can correct the page data, the storage device corrects the first data and stores the first data after error correction and the error correction code generated based on the first data after error correction. If the storage device cannot correct the first data, the storage device generates an interrupt signal corresponding to the first data to cause the electronic device to stop the service corresponding to the first data.

[0109] Optionally, the first data may be error corrected according to the following feasible implementation method: the bit width of the data that is different between the first error correction code and the third error correction code is obtained, and when the bit width is less than or equal to a preset threshold, the first data is error corrected. For example, if there is a 1-bit difference in data between the first error correction code and the third error correction code, the storage device may perform error correction on the first data (e.g., the first error correction code and the third error correction code are both ECC data, and the storage device may determine the location of the error in the first data through the parity bit in the ECC data, and then correct the first data).

[0110] Optionally, an interrupt signal corresponding to the first data may be generated according to the following feasible implementation method: obtaining the bit width of the data that is different between the first error correction code and the third error correction code, and generating an interrupt signal corresponding to the first data when the bit width is greater than a preset threshold. For example, if there is a 2-bit difference in data between the first error correction code and the third error correction code, the storage device cannot perform error correction processing on the first data, and the storage device may generate an interrupt signal to stop the electronic device from using the service of the first data.

[0111] The disclosed embodiment provides a data processing method, wherein a storage device receives first data and a third error correction code sent by an electronic device, the storage device generates a first error correction code based on the first data, and verifies the first data based on the first error correction code and the third error correction code to obtain a second verification result, and the storage device processes the first data and the first error correction code based on the second verification result. In this way, since the first error correction code is obtained by the storage device receiving the first data sent by the electronic device, the error of the first data during the transmission process can be found through the first error correction code and the third error correction code, and when the electronic device obtains the first data and the first error correction code from the storage device, since the first error correction code is the error correction code generated before the storage device stores the first data, the error of the first data during the storage process can be found through the first error correction code, thereby improving the accuracy of data verification.

[0112] exist Figure 2 Based on the embodiment shown in FIG. 1 , after the storage device stores the first data and the first error correction code according to the second verification result, the storage device may also send the first data to the electronic device. Figure 7 , a process of a storage device sending first data to an electronic device is described.

[0113] Figure 7 A schematic diagram of a method for sending first data provided by an embodiment of the present disclosure. Figure 7 The method flow includes:

[0114] S701: A storage device receives a data read request for first data sent by an electronic device.

[0115] Optionally, when the electronic device reads the first data, it can send a data read request to the memory device, wherein the data read request may include an identifier of the first data. The memory device can determine the data to be obtained through the identifier of the first data and send the data to the electronic device.

[0116] S702: In response to a data read request, the storage device sends first data and a first error correction code to the electronic device, so that the electronic device verifies the first data according to the first error correction code.

[0117] Optionally, the storage device can obtain the stored first data and the first error correction code corresponding to the first data through the identifier of the first data in the data read request. After the electronic device receives the first data and the first error correction code, it can verify the first data through the first error correction code.

[0118] Optionally, before the storage device sends the first data and the first error correction code to the electronic device, the storage device can generate a fourth error correction code from the first data, and verify the first data through the fourth error correction code and the first error correction code, and then determine whether the first data is erroneous during the storage process through the verification result. For example, before the storage device sends the first data to the electronic device, the storage device can generate a fourth error correction code based on the first data. Since the first error correction code is an error correction code generated before the storage device stores the first data, whether the first data is erroneous during the storage process can be determined through the degree of matching between the first error correction code and the fourth error correction code.

[0119] Optionally, if the first error correction code is the same as the fourth error correction code, it means that the first data is not wrong during the storage process of the storage device; if the first error correction code is different from the fourth error correction code, it means that the first data is wrong during the storage process. When the first data is not wrong, the memory device sends the first data and the first error correction code corresponding to the first data to the electronic device. For example, if the first data is wrong during the storage process, the memory device can correct the first data or generate an interrupt signal; if the first data is not wrong during the storage process, the memory device can send the first data and the first error correction code to the electronic device; the electronic device generates the second error correction code through the first data, and verifies the first data through the first data and the second error correction code; if the first data is not wrong, the electronic device processes the business corresponding to the first data; if the first data is wrong, it means that the first data is wrong during the sending process. In this way, when the first data is wrong, the electronic device can accurately determine the fault location, thereby improving the efficiency of fault repair.

[0120] The disclosed embodiment provides a method for a storage device to send first data to an electronic device, wherein the storage device receives a data read request for the first data sent by the electronic device, and in response to the data read request, the storage device sends the first data and a first error correction code to the electronic device, so that the electronic device verifies the first data according to the first error correction code. In this way, when the electronic device obtains the first data and the first error correction code from the storage device, since the first error correction code is an error correction code generated before the storage device stores the first data, the first error correction code can be used to find out the error of the first data during the storage process and the error during the sending process, thereby improving the accuracy of data verification.

[0121] Based on any of the above embodiments, Figure 8 , the process of the above data processing method is explained.

[0122] Figure 8 A process diagram of a data processing method provided by an embodiment of the present disclosure. Figure 8 , including: a system on chip and a memory. Optionally, the system on chip and the memory are both devices in an electronic device. After the system on chip obtains the first data, it generates a third error correction code according to the first data, and sends the first data and the third error correction code to the memory. When the memory receives the first data and the first error correction code sent by the system on chip, it generates the first error correction code according to the first data, and verifies the first data by using the first error correction code and the third error correction code. When the first data passes the verification, the memory can store the first error correction code and the first data.

[0123] See also Figure 8 When the electronic device needs to use the first data, the system on chip can send a request message for the first data to the memory. When the memory receives the request message for the first data, it can send the first data and the first error correction code corresponding to the first data to the system on chip. After the system on chip receives the first data and the first error correction code, it can generate a second error correction code according to the first data, and verify the first data again through the first error correction code and the second error correction code. When the first data is verified, the electronic device can perform business processing according to the first data. Optionally, during the verification process of the first data by the memory and the system on chip, if the verification fails, the memory and the system on chip can correct the first data, or generate an interrupt signal for the first data, so as to improve the reliability of the data. In this way, since the first error correction code is the error correction code generated when the storage device stores the first data, and the second error correction code is the error correction code generated when the electronic device obtains the first data from the memory device, the first error correction code and the second error correction code can be used to identify problems in the transmission process of the first data and problems in the storage process of the first data in the storage device, thereby improving the accuracy of data verification.
