Abstract
Description
Technical Field
[0001] This application relates to the field of receiver chip technology, and more specifically, to a method and apparatus for automatic repair of receiver chips. Background Technology
[0002] High-frequency receiver chips require configuration registers to set up the chip, which determines the frequency band, rate, format, and other attributes of the received radio frequency signals. Therefore, for vehicle remote control ECUs (Electronic Control Units), ensuring the accuracy of the register values within the chip is crucial, as it will affect whether the chip's receiving function is normal.
[0003] The registers of a high-frequency receiver chip remain unchanged when there is no power loss and no operation. However, in practical applications, under extreme conditions such as high and low temperatures and electromagnetic interference, the register values may be altered, causing the ECU module to lose its remote control function. Furthermore, it lacks an automatic recovery function; it can only fully recover by powering off and on again. This is accompanied by symptoms such as the vehicle not responding when the remote control is pressed, and abnormal tire pressure monitoring, resulting in a poor user experience for automotive end-users. Therefore, how to automatically repair the receiver chip has become a pressing technical problem to be solved. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0043] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and accompanying drawings of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.
[0044] This application discloses an automatic repair method and apparatus for receiver chips, which can automatically repair receiver chips. The embodiments of this application are described in detail below.
[0045] Figure 1 This document illustrates a flowchart of an automatic repair method for a receiver chip provided in an embodiment of this application. Figure 1 As shown, the method includes the following steps:
[0046] S110: Determine the target register for the corresponding receiving function in the receiving chip.
[0047] Typically, a receiver chip may include multiple registers, and each register has a slightly different function. It is understood that only the register corresponding to the receiving function affects the receiver chip's receiving capability. Therefore, in this embodiment, each register in the receiver chip corresponding to the receiving function can be identified as a target register. Anomalies in each target register can be detected and repaired, thereby restoring the receiver chip's receiving capability. For example, multiple target registers affecting the RF receiving function can be identified by querying the chip configuration sheet.
[0048] S120: Initialize the register error count value and, according to the preset query order of each target register, use the first target register as the current register.
[0049] It is understandable that various abnormal situations may exist in multiple target registers. Specifically, only a few registers may be abnormal, or most registers may be abnormal. Correspondingly, the causes of the abnormalities are also different. When a few registers are abnormal, it may simply be due to abnormal data in the register itself, or a general chip problem caused by minor extreme conditions such as high or low temperatures or electromagnetic interference. However, when most registers are abnormal, it is very likely that the receiving chip has encountered a more serious extreme condition, resulting in a serious chip problem.
[0050] In this embodiment, to improve repair efficiency, different repair methods can be used to repair the receiving chip for different abnormal situations, i.e., different numbers of registers experiencing abnormalities. Therefore, while performing abnormality detection on each target register sequentially, the number of registers experiencing abnormalities can be counted simultaneously, which can be called the register error count.
[0051] Specifically, you can first initialize the register error count value, such as setting it to 0, and then, according to the preset query order of each target register, use the first target register as the current register to perform error detection on the first target register.
[0052] In one implementation, when the number of target registers is N, a query array Reg[n] can be generated in RAM (Random Access Memory), and the first register queried is Reg1.
[0053] S130: Check if there is an anomaly in the current register.
[0054] For each target register, there is a corresponding correct value. In this embodiment, the correct value of each target register can be pre-stored. Therefore, when performing anomaly detection on the current register, the pre-stored correct value of the current register can be obtained, and the current value of the current register can be determined. If the current value and the correct value are inconsistent, it is determined that the current register is abnormal.
[0055] S140: When there is an error in the current register, update the register error count and use the corresponding processing method to repair the receiving chip according to the register error count.
[0056] When an anomaly is detected in the current register, the register error count can be updated first, for example, by incrementing the register error count by 1. Furthermore, based on the register error count, a corresponding processing method can be used to repair the receiving chip. For instance, based on the pre-stored correct values of each target register, if the register error count is low, only the current register can be reassigned; if the register error count is high, each target register can be reassigned.
[0057] In one implementation, when the register error count is less than or equal to a preset threshold, it indicates that there may only be an anomaly in the register data itself, or a general chip problem caused by minor extreme conditions such as high or low temperatures or electromagnetic interference. In this case, only the current register can be restored, and then the driver interface can be called to restore the chip's receiving function. After restoring the current register, it can be further determined whether the current register is the last register. If not, the next register is taken as the current register according to the query order, and the process of checking whether the current register has an anomaly is returned, until the current register is the last register, indicating that anomaly detection has been performed on all registers. In this case, the anomaly detection of the registers ends.
[0058] When the register error count exceeds a preset threshold, it indicates that the receiver chip may have encountered a serious problem due to a severe extreme condition. In this case, the receiver chip can be reset and initialized. In other words, when the receiver chip has a serious problem, it can be fully initialized to fix all issues.
[0059] S150: When there is no exception in the current register, determine whether the current register is the last register. If not, take the next register as the current register according to the query order, and return to step S130 to check whether there is an exception in the current register.
[0060] If there is no exception in the current register, it can be determined whether the current register is the last register. If not, it means that not all registers have been checked. In this case, the next register can be used as the current register according to the query order, and the process can return to step S130 to check whether there is an exception in the current register. If the current register is the last register, it means that all registers have been checked for exceptions, and the register exception check ends.
[0061] In this embodiment, anomaly detection can be performed sequentially on the target registers corresponding to the receiving function in the receiving chip. When an abnormal register is detected, the receiving chip is repaired in a corresponding manner based on the number of abnormal registers. In other words, automatic repair can be achieved without powering the receiving chip back on and off. Furthermore, repairing the receiving chip in a corresponding manner based on the number of abnormal registers improves the anomaly repair efficiency of the receiving chip while ensuring stable recovery. In addition, detecting one current register per cycle, i.e., performing anomaly detection in cycles, has minimal impact on the operating load rate. Moreover, the above diagnostic logic can be widely used for most RF chips, and it can also be applied to chips with internal state storage with slight modifications, thus improving the applicability of automatic repair of the receiving chip.
[0062] exist Figure 1 Based on the illustrated embodiment, as an implementation of this application, after determining that the current register is the last register, that is, after performing anomaly detection on all target registers, the receiving status of the receiving chip can be further detected to confirm whether the receiving status of the receiving chip is normal.
[0063] Specifically, the receiving chip's receiving status can be queried, and the receiving chip can be repaired if an anomaly is found. For example, in one implementation, if the Receive state is normal, then a non-Receive state indicates an abnormal receiving chip status. In this case, the receiving chip can be reset and initialized to restore its normal receiving function. After resetting and initializing the receiving chip, or when the receiving chip's receiving status is determined to be normal, it indicates that both the registers and the receiving chip have completed their checks in the current cycle, and the next cycle can begin.
[0064] In this embodiment, after performing anomaly detection on the register, the receiving status of the receiving chip can be further queried, thereby enabling a comprehensive test of the receiving chip and ensuring that the receiving function of the receiving chip operates normally.
[0065] The automatic repair method for the receiver chip provided in this application will be described below with reference to a specific embodiment.
[0066] The main anomalies of high-frequency receiver chips can be categorized into two types: register data anomalies and chip self-state anomalies. To address this, a background monitoring interface can be provided in the software to identify the cause of the fault and perform specific recovery measures based on the specific circumstances. In this embodiment, the registers and chip state can be read through the software interface and compared with the correct state stored in the software to determine the specific anomaly and repair it. Specifically, this may include the following situations:
[0067] Scenario 1: When more than 10% of registers are found to be faulty, the chip is considered to have a serious problem, and the corresponding handling method is to reinitialize the chip.
[0068] Scenario 2: When less than 10% of register errors are detected, the chip is considered to have a general problem. Only the faulty registers are repaired to restore the chip's receiving function.
[0069] Scenario 3: When an abnormal state of the chip is detected, it is considered that the chip has a serious problem, and the corresponding handling method is to reinitialize the chip.
[0070] For cases one and three, which are defined as serious problems, the software will allocate bus resources for reinitialization. The time required to restore each register one by one is Tcycle*N (where N is the total number of registers and Tcycle is the recovery cycle time of a single register). Reinitialization is faster, taking only 15% of the time required for individual restoration, that is, Tcycle*N*15% is enough to restore the high-frequency reception function.
[0071] For scenario two, a general problem, recovery can be achieved within m cycles (where m is the number of faulty registers), taking Tcycle*n time, resulting in faster and more targeted recovery.
[0072] refer to Figure 2 The overall repair process is as follows:
[0073] 1. The software identifies N key registers that affect the RF receiving function through the chip configuration sheet.
[0074] 2. Based on the key registers identified in step 1, generate a query array Reg[n] in RAM.
[0075] 3. Query the first register Reg1 and compare it with the preset correct value. If there is no problem, skip this cycle; if there is a problem, only restore that register, and the error count is recorded in the background. err It then calls the driver interface to restore the chip's receiving function.
[0076] 4. In the next software cycle, follow step 3 to query the second register Reg2, and so on.
[0077] 5. Monitor the error count every cycle. When the error count is detected... err When the value is greater than N*10%, the chip is reset and fully initialized.
[0078] 6. Following steps 4 and 5, the last register Reg of the data is detected sequentially. n .
[0079] 7. Check the status of the high-frequency receiver chip. Skip the normal receiving state; other states are considered chip malfunctions, and the chip is reset and reinitialized. This part is related to the specific high-frequency receiver chip mode and can be adjusted according to the actual situation. For example, in one implementation, the Receive state is the normal receiving state; the Idle state is the initial state after power-on, with no receiving function; and the Standby state is the low-power state, with no receiving function.
[0080] 8. Following steps 2-7, the chip will run for an extended period during its lifecycle to monitor the chip and restore its functionality.
[0081] The above register check process, running at the Fbasic clock frequency, takes approximately (1 / Fbasic)*400 seconds per cycle. The query operation within the Tcycle cycle has a load rate of (1 / Fbasic)*400 / Tcycle. Generally, a software load rate greater than 80% is considered a poor software state; however, the load rate of this function is far less than 80%.
