[0056] The power-off notification mechanism (PON) of eMMC is used to notify eMMC before the device is powered off, so as to complete all unfinished operations before power-off, thereby avoiding data loss and device damage. By optimizing the response time of PON, it can be ensured that the storage device can quickly enter the sleep state or be reawakened when the system needs it, thereby improving the performance of the entire device. However, there is a lack of an effective method for testing the PON of eMMC in the existing technical solutions.

[0057] Example 1

[0058] The embodiment of the present invention provides a method for testing the performance of an embedded multimedia card, effectively solving the problem in the prior art solution that there is a lack of an effective test method for the power-off notification mechanism of the embedded multimedia card. Figure 1 It is the first schematic diagram of the process of the method for testing the performance of the embedded multimedia card provided by the embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0059] S100. Conduct a benchmark test on the embedded multimedia card to obtain benchmark performance data.

[0060] In the embodiment of the present invention, it is necessary to ensure that the hardware test equipment works properly before the test. The hardware test equipment includes but is not limited to a power supply, a test board, and an embedded multimedia card storage device. The power parameter configuration of the power supply can be adjusted so as to dynamically adjust the voltage and current during the test. The embedded multimedia card storage device is a storage device based on eMMC5.0. eMMC5.0 (Embedded MultiMediaCard 5.0) is a storage standard used for embedded storage devices, such as flash memories in smart phones and tablet computers.

[0061] At the same time, set the temperature and humidity of the test environment according to the actual usage conditions to ensure the accuracy and reliability of the test results. Figure 2 It is the working flowchart of the hardware test equipment in the embodiment of the present invention, as Figure 2 shown, the working process includes:

[0062] First, apply power to the embedded multimedia card storage device through the power supply. The PON hardware signal will be activated. The PON hardware signal usually includes a dedicated pin or a group of pins, which are directly connected to the power management circuit. When the PON pin detects the power-on, it will trigger the internal circuit and send a trigger signal to notify the control logic of the embedded multimedia card storage device. The internal logic circuit starts to work, and at this time, device initialization and abnormal power detection can be performed.

[0063] During the power supply stability period, the power-off notification mechanism continuously monitors the power supply status. When a power supply fluctuation or power-off is detected, the PON hardware signal can quickly detect this change. Once a power supply anomaly is detected, the embedded multimedia card storage device can immediately take measures, such as interrupting the current operation, closing the data interface, or saving the internal state to a non-volatile memory, to prevent data corruption. When the power supply resumes stability, the PON hardware signal is triggered again, and the device can resume operations from the previously saved state, thus ensuring data consistency and integrity. Through this mechanism, the embedded multimedia card device can effectively protect data in an environment with unstable power supply and prevent data loss or corruption caused by power supply problems.

[0064] Figure 3 It is the second schematic diagram of the performance test method flow of the embedded multimedia card provided by the embodiment of the present invention. As Figure 3 shown, the benchmark test mainly includes the following steps:

[0065] S110. Initialize the embedded multimedia card and configure the initial parameters of the embedded multimedia card.

[0066] In the embodiment of the present invention, after receiving the PON hardware signal, the control logic of the embedded multimedia card will be initialized to configure the initial parameters of the embedded multimedia card, such as device configuration, wake-up of the memory array, and preparation of the data interface. If the device was previously in a sleep or low-power mode, the PON hardware signal will wake it up.

[0067] S120. Perform read and write tests on the embedded multimedia card under stable power supply conditions to obtain the benchmark response time and benchmark performance data.

[0068] To ensure the stability and reliability of the storage device performance, it is necessary to perform read and write tests on the embedded multimedia card under stable power supply conditions, record key performance indicators such as response time and throughput, so as to obtain the benchmark response time and benchmark performance data. Optionally, the test can be repeated multiple times and the average value can be taken to improve the accuracy of the data.

[0069] S200. Dynamically adjust the power supply during the read and write operations of the embedded multimedia card according to the benchmark performance data to obtain the test performance data of different adjustment strategies.

[0070] In the embodiment of the present invention, the power supply is dynamically adjusted according to the benchmark performance data to test the response time of the PON function under different power supply adjustment strategies. Figure 4 It is the third schematic diagram of the performance test method flow of the embedded multimedia card provided by the embodiment of the present invention. As Figure 4 shown, the dynamic power supply adjustment includes the following steps:

[0071] S210. Gradually adjust the power supply voltage during the read / write operation of the embedded multimedia card to simulate voltage fluctuations.

[0072] In an embodiment of the present invention, the first power supply adjustment strategy is the power supply fluctuation strategy, that is, the power supply experiences multiple fluctuations during the power-on process. Specifically, gradually adjust the power supply voltage during the read / write operation of the embedded multimedia card to simulate voltage fluctuations. For example, the power supply fluctuates within 0 - 200 milliseconds, first rises to 50%, then drops to 25%, and then rises to 100%, and monitor the PON response time and the activation situation of the data protection mechanism.

[0073] S220. After power-off during the read / write operation of the embedded multimedia card, quickly power on.

[0074] In an embodiment of the present invention, the second power supply adjustment strategy is the quick power-on strategy, that is, the power supply quickly reaches a stable state within a short time. Specifically, suddenly power off during the read / write operation of the embedded multimedia card, and then quickly power on. For example, within 0 - 100 milliseconds after power-off, the power supply rises from 0% to 100%, and record the PON function response time and the activation situation of the data protection mechanism.

[0075] S230. After power-off during the read / write operation of the embedded multimedia card, slowly power on.

[0076] In an embodiment of the present invention, the third power supply adjustment strategy is the slow power-on strategy, that is, the power supply gradually reaches a stable state within a certain time. Specifically, suddenly power off during the read / write operation of the embedded multimedia card, and then slowly power on. For example, within 0 - 500 milliseconds after power-off, the power supply linearly rises from 0% to 100%, and record the PON function response time and the activation situation of the data protection mechanism.

[0077] S300. Analyze the response performance of the power-off notification mechanism function of the embedded multimedia card according to the test performance data, and obtain the performance analysis results of different adjustment strategies.

[0078] Figure 5 It is the fourth schematic diagram of the performance test method flow of the embedded multimedia card provided by the embodiment of the present invention. As Figure 5 shown, the performance analysis specifically includes the following steps:

[0079] S310. Obtain the power-off notification signal reception time and the embedded multimedia card preparation time according to the test performance data.

[0080] In the embodiments of the present invention, under the power fluctuation strategy, when the power supply rises to 50%, the reception time of the first power-off notification signal is 50 milliseconds. When the power supply drops, the embedded multimedia card attempts to start but is not ready. When the power supply rises to 100% again, the reception time of the second power-off notification signal is 150 milliseconds, and the preparation time of the embedded multimedia card is 250 milliseconds. The reception time of the power-off notification signal and the preparation time of the embedded multimedia card under the fast power-on strategy are 10 milliseconds and 20 milliseconds respectively. The reception time of the power-off notification signal and the preparation time of the embedded multimedia card under the slow power-on strategy are 200 milliseconds and 300 milliseconds respectively.

[0081] S320. Calculate the response time according to the reception time of the power-off notification signal and the preparation time of the embedded multimedia card.

[0082] The PON function response time is the time when the embedded multimedia card device receives the PON signal and is ready, that is, the sum of the reception time of the power-off notification signal and the preparation time of the embedded multimedia card. In the embodiments of the present invention, the response time of the power fluctuation strategy is 450 milliseconds, and the time of the first attempt failure is considered at this time. The response time of the fast power-on strategy is 30 milliseconds, and the response time of the slow power-on is 500 milliseconds.

[0083] S330. Analyze the performance of different adjustment strategies according to the response time to obtain the performance analysis result.

[0084] In the embodiments of the present invention, due to voltage fluctuations in the power fluctuation strategy, the PON function response time is unstable, which may cause the embedded multimedia card device to attempt to start multiple times, affecting the device stability, and the total response time is relatively long. It is not recommended for scenarios with high requirements for startup speed and stability. The PON function response time of the fast power-on strategy is the shortest because the power supply quickly stabilizes, which is suitable for application scenarios with high requirements for startup speed. Due to the power supply taking a longer time to reach the stable state in the slow power-on strategy, the PON function response time is longer, but it provides a more stable power environment, which may be more beneficial to the long-term reliability of the embedded multimedia card.

[0085] S400. Optimize the power-off notification mechanism of the embedded multimedia card according to the performance analysis result.

[0086] In the embodiments of the present invention, adjust the parameters of the power-off notification mechanism of eMMC5.0 according to the performance analysis result, mainly including adjusting the response threshold of the power-off notification mechanism and optimizing the data protection strategy, which usually need to be carried out according to specific application scenarios and requirements. Figure 6 It is the fifth schematic diagram of the performance test method flow of the embedded multimedia card provided by the embodiments of the present invention. As Figure 6 shown, the parameter optimization specifically includes the following steps:

[0087] S410. Adjust the response threshold of the power-off notification mechanism according to the wake-up rate of the embedded multimedia card.

[0088] The response threshold of the power-off notification mechanism determines when the embedded multimedia card wakes up from the low-power state. Adjusting this parameter can optimize the response time and power consumption of the storage device. Figure 7 It is the sixth schematic diagram of the performance test method flow of the embedded multimedia card provided by the embodiment of the present invention. As Figure 7 shown, the adjustment of the response threshold of the power-off notification mechanism includes the following steps:

[0089] S411. If the wake-up rate of the embedded multimedia card is greater than or equal to the first set threshold, increase the response threshold of the power-off notification mechanism.

[0090] For non-real-time devices or systems, if the requirement for startup speed is not high, if the wake-up rate is greater than or equal to the first set threshold, it means that the storage device is easy to wake up. At this time, the response threshold of the power-off notification mechanism can be increased, so that the embedded multimedia card is activated only when receiving more or stronger wake-up signals, thereby reducing the false wake-up rate to save power. Optionally, the first set threshold can be set according to the actual situation.

[0091] S412. If the wake-up rate of the embedded multimedia card is less than the first set threshold, decrease the response threshold of the power-off notification mechanism.

[0092] For devices or systems that require fast response, such as a real-time operating system RTOS, if the wake-up rate of the embedded multimedia card is less than the first set threshold, it means that the storage device is not easy to wake up. At this time, the response threshold of the power-off notification mechanism can be decreased, so that the embedded multimedia card can respond to smaller wake-up signals and achieve fast wake-up of the device.

[0093] S420. Adjust the strength of the data protection policy according to the data writing speed of the embedded multimedia card.

[0094] The data protection policy determines the speed and frequency at which the embedded multimedia card transfers data from the cache to non-volatile storage before power-off. Figure 8 It is the seventh schematic diagram of the performance test method flow of the embedded multimedia card provided by the embodiment of the present invention. As Figure 8 shown, the adjustment of the data protection policy specifically includes the following steps:

[0095] S421. If the data writing speed is less than the second set threshold, increase the data synchronization frequency of the embedded multimedia card.

[0096] In an environment with unstable power supply, it is necessary to ensure that data is not lost. If the data writing speed is less than the second set threshold, the data synchronization frequency is relatively low, resulting in a relatively high risk. At this time, increase the data synchronization frequency of the embedded multimedia card, quickly synchronize the data to the non-volatile storage, and reduce the risk of data loss. Optionally, the second set threshold can be set according to the actual situation.

[0097] S422: If the data writing speed is greater than or equal to the second set threshold, then reduce the data synchronization frequency of the embedded multimedia card.

[0098] In a device or system with stable power supply and high requirements for startup speed, if the data writing speed is greater than or equal to the second set threshold, it will result in a high data synchronization frequency, affecting the device performance. At this time, reduce the data synchronization frequency of the embedded multimedia card, thereby reducing the impact of data synchronization on the device performance.

[0099] S500: Test the optimized embedded multimedia card under various power fluctuation conditions to obtain a performance test report.

[0100] In the embodiment of the present invention, finally test the optimized embedded multimedia card under various power fluctuation conditions to ensure that the optimized power-off notification function can quickly respond and protect data in various situations.

[0101] Power fluctuations can affect the embedded multimedia card device and need to be managed and tested through the power-off notification function. Such power fluctuations can include the following various situations:

[0102] Power fluctuations during device startup and shutdown. For example, when the device starts up, the power supply may be unstable, resulting in an instantaneous rise or fall in voltage; during the device shutdown process, the power supply may suddenly cut off.

[0103] Battery power fluctuations. For example, when the battery power is about to run out, the power output may be unstable; during battery replacement or when the battery contact is poor, the power supply may be interrupted briefly.

[0104] External power adapter problems. For example, the power adapter is overheated, damaged, or the output voltage is unstable; for example, the power cord is damaged or the connection is loose, which may cause the power supply to be interrupted.

[0105] System load changes. For example, when the system runs high-load applications, the power demand increases, which may cause the power supply to be unstable; during multitasking, the power demand changes frequently, which may cause power fluctuations.

[0106] Environmental factors. For example, extreme temperature conditions may cause changes in the performance of power supply equipment; a high-humidity environment may cause internal circuit problems in power supply equipment.

[0107] Grid problems, such as unstable grid frequency, may affect the output of the power adapter; fluctuations in grid voltage will affect the power supply.

[0108] To address the above power fluctuations, the power-off notification function of the embedded multimedia card can adopt the following optimization measures: The embedded multimedia card device can detect the power on and off through the PON hardware signal to quickly respond to power fluctuations. When the power is unstable, the embedded multimedia card device can automatically enter the protection mode and stop all operations to prevent data damage. When a power fluctuation occurs, the embedded multimedia card device can interrupt the current transaction and resume operations after the power stabilizes. The embedded multimedia card device can detect power failures and protect data through hardware or software mechanisms.

[0109] After completing tests under various power fluctuation conditions, a test report can be generated, including the test process, results, optimization strategies, and final performance evaluation. Optionally, the parameters of the optimized power-off notification mechanism can be applied to the actual product for on-site testing to verify the actual effect of the optimization strategy.

[0110] The performance test method for the embedded multimedia card provided by the embodiments of the present invention can dynamically adjust the test conditions and parameters according to real-time feedback, which can accelerate the startup time of the storage device, reduce the time from the sleep state to the fully operational state of the device, and improve the overall responsiveness of the storage system. When the storage device can respond to the power-off notification mechanism signal faster, the efficiency of the entire storage system will also increase because other components do not need to wait for the storage device to be ready, ensuring that the storage device can provide a consistent response time and performance under different working conditions, which is crucial for the stability of the storage system. At the same time, optimizing the response time of the power-off notification mechanism helps to better manage the power of the device, reduce unnecessary power consumption, and extend the battery life.

As Figure 10 shown, the electronic device 1000 may include: a processor 1010, a communications interface 1020, a memory 1030, and a communication bus 1040. Among them, the processor 1010, the communications interface 1020, and the memory 1030 communicate with each other through the communication bus 1040. The processor 1010 may call the logic instructions in the memory 1030 to execute the steps of the performance test method for the embedded multimedia card as described in the above embodiments.
