[0053] 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.

[0054] The embodiments described in some embodiments of the present disclosure below 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.

[0055] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0056] In embedded heterogeneous chip systems, since the storage space and necessary hardware need to be initialized during the system cold start process, this process often takes several seconds to several minutes, making it difficult to meet application scenarios where the startup time is sensitive.

[0057] In related technologies, in order to meet the needs of fast startup of embedded systems, some hot startup methods are used in system design to save boot time. For example, STR (Suspend-to-RAM, software suspend / hibernate wakeup), when executing software suspension, the current state of the system will be saved to RAM (Random Access Memory), and most hardware devices will be turned off to minimize power consumption. During the recovery process, the state saved in RAM will be restored to return the system to the state before suspension. Compared with the cold start method, the main advantage of hot start is fast startup speed, which can shorten the startup speed by about 90% while only keeping RAM power supply, but it will also bring some memory fragmentation and dirty data problems.

[0058] In view of the above technical problems, the embodiments of the present disclosure provide a system memory cleaning method, device, equipment, storage medium and program product, which obtain the number of hot start times of the target system when the target system is in a dormant state, and control the target processor of the target system to restart within the shutdown time window when the number of hot start times meets a first preset condition. Thus, the target system's corresponding running data can be cleared by controlling the target processor of the target system to restart without affecting user use, thereby clearing memory fragments and dirty data caused by the hot start of the target system.

[0059] Figure 1 is a flowchart of a system memory cleaning method according to an exemplary embodiment. Figure 1 As shown, the method can be used in a terminal and may include the following steps.

[0060] In step S101 , when the target system is in a dormant state, the number of hot boots of the target system is obtained.

[0061] In this embodiment, the target system may be an embedded heterogeneous chip system, which may be applied to automotive controllers or industrial and medical-related embedded systems. After the target system is awakened, if no wake-up source is received within a preset time, it may enter a dormant state. Among them, the range of the preset time can be set according to the specific situation, for example, the preset time may be 5 minutes to 10 minutes. When the target system is in a dormant state, the number of hot starts of the target system is obtained, which can minimize the impact on user use. Among them, the hot start may be STR, and when the execution software is suspended, the current state of the system will be saved in RAM, and most of the hardware devices will be turned off to minimize power consumption. During the recovery process, the state saved in RAM will be restored to return the system to the state before the suspension. The hot start counter can be used to count the number of hot starts of the target system to obtain the number of hot starts of the target system.

[0062] In step S102, when the number of hot starts meets a first preset condition, the target processor of the target system is controlled to restart within the shutdown time window.

[0063] In this embodiment, the first preset condition is used to determine whether it is necessary to control the target processor of the target system to restart, and the first preset condition may be a hot start number threshold or a hot start number interval. Hot start will cause memory fragmentation and dirty data. Through repeated hot starts, a large amount of storage data will be accumulated, and most of the large amount of storage data caused by hot starts are dynamic storage data. Based on the number of hot starts, it is determined whether the operating data corresponding to the target system is clear, and the memory fragmentation and dirty data caused by the hot start of the target system can be cleared in a timely manner. And by controlling the target processor of the target system to restart, the dynamic storage data corresponding to the target system can be cleared, which can greatly clear the memory fragmentation and dirty data stored due to the hot start of the target system. Among them, the target processor may be an A core. Among them, the shutdown time window is a preset time period, which can be determined based on the car usage time data of a large number of users, and the preset time period can be the time period when users use the car the least. For example, the preset time period may be from 2 am to 5 am.

[0064] In a possible implementation, the method may further include:

[0065] When the number of hot starts meets the second preset condition, the target system is controlled to be forced to cold start.

[0066] In this embodiment, the second preset condition is used to determine whether to control the target system to force a cold start. The second preset condition may be a hot start number threshold. The cold start may be to restart both the A core and the M core of the target system to clear the dynamic storage data and static storage data corresponding to the target system, so that the dynamic storage data stored in the running storage of the A core and the static storage data stored in the running storage of the M core can be cleared, so that the memory cleaning of the system is more thorough.

[0067] Figure 2 is a flowchart of a method for restarting a target processor according to an exemplary embodiment. Figure 2 As shown, in a possible implementation manner, when the number of hot starts meets the first preset condition, the method for controlling the target processor of the target system to restart may include the following steps:

[0068] In step S201, when the number of hot starts is greater than the first target number and less than the second target number, a shutdown delay corresponding to the target timer is determined according to the shutdown time window and the sleep time.

[0069] In step S202, when the timing duration of the target timer is equal to the shutdown delay, the target processor of the target system is controlled to restart.

[0070] In this embodiment, the first preset condition may be that the number of hot starts is greater than the first target number and less than the second target number. The first target number and the second target number may be set according to actual conditions. For example, the first target number may be 40 times, and the second target number may be 60 times. In the case where the number of hot starts is greater than the first target number and less than the second target number, although the stored data is large, it does not affect the normal use of the user, and the target processor can be restarted at an appropriate time that does not affect the use of the user. For example, the shutdown delay corresponding to the target timer can be determined according to the shutdown time window and the sleep time. The sleep time is the time corresponding to the system entering sleep. The shutdown delay is the delay time for restarting the target processor, which can be timed by the target timer. When the timing time of the target timer is equal to the shutdown delay, the restart can be triggered to control the restart of the target processor of the target system. The shutdown delay is used to control the restart time of the target processor within the shutdown time window.

[0071] Figure 3 is a schematic diagram of a shutdown delay according to an exemplary embodiment. Figure 3 As shown, in a possible implementation manner, according to the shutdown time window and the sleep time, the method for determining the shutdown delay corresponding to the target timer may be:

[0072] When the sleep time is before the start time of the closest first shutdown time window, the time difference between the sleep time and the start time of the first shutdown time window is determined as the shutdown delay corresponding to the target timer.

[0073] In this embodiment, the first shutdown time window is a shutdown time window closest to the sleep time, and the first shutdown time window may include a start time and an end time. For example, if the first shutdown time window is from 2 a.m. to 5 a.m., the start time of the first shutdown time window is 2 a.m. and the end time is 5 a.m. In the case where the sleep time is before the start time of the closest first shutdown time window, a shutdown delay needs to be set so that the restart time of the target processor is controlled within the shutdown time window. In order to shorten the shutdown delay as much as possible, the time difference between the sleep time and the start time of the first shutdown time window can be determined as the shutdown delay corresponding to the target timer.

[0074] In a possible implementation, according to the shutdown time window and the sleep time, a method for determining the shutdown delay corresponding to the target timer may be:

[0075] When the sleep time is within the closest first shutdown time window, the shutdown delay corresponding to the target timer is set to 0.

[0076] In this embodiment, when the sleep time is within the closest first shutdown time window, the target processor can be directly restarted. In order to shorten the shutdown delay as much as possible, the shutdown delay corresponding to the target timer can be set to 0, that is, the restart of the target processor is triggered immediately.

[0077] Figure 4 is another shutdown delay schematic diagram according to an exemplary embodiment. Figure 4 As shown, in a possible implementation manner, according to the shutdown time window and the sleep time, the method for determining the shutdown delay corresponding to the target timer may be:

[0078] When the sleep time is after the end time of the closest first shutdown time window, the time difference between the sleep time and the start time of the second shutdown time window is determined as the shutdown delay corresponding to the target timer, and the second shutdown time window is the next shutdown time window of the first shutdown time window.

[0079] In this embodiment, the second shutdown time window is the next shutdown time window of the first shutdown time window. One shutdown time window may be set every day, or multiple shutdown time windows may be set every day. In the case where the sleep time is after the end time of the closest first shutdown time window, the restart of the target processor cannot be controlled within the first shutdown time window. In order to shorten the shutdown delay as much as possible and reduce the data storage pressure, the time difference between the sleep time and the start time of the second shutdown time window may be determined as the shutdown delay corresponding to the target timer.

[0080] In a possible implementation manner, when the number of hot starts meets the second preset condition, the method for controlling the target system to force a cold start may be:

[0081] When the number of hot starts is greater than the second target number, the target system is controlled to be forced to cold start after a preset time.

[0082] In this embodiment, the second preset condition may be that the number of hot starts is greater than the second target number, and the second target number may be set according to actual conditions, for example, the second target number may be 60. When the number of hot starts is greater than the first target number, the user may be using the target system during the shutdown time window every day. This causes the target system to be in a dormant state that cannot be within the shutdown time window, and the target system cannot restart the target processor within the shutdown time window. The number of hot starts will exceed the first target number and continue to increase, causing greater data storage pressure and affecting the user's experience of the target system. When the number of hot starts is greater than the second target number, the data storage pressure is greater. In order to avoid affecting the user's experience, the target system can be controlled to force a cold start after a preset time. That is, as long as the target system is in a dormant state for a certain period of time, a forced cold start can be performed, and no restart is sought within the shutdown time window. Among them, the preset time can be set according to actual conditions, for example, 15 minutes. The preset time is used to avoid a forced cold start when the user actively wakes up the target system again within the preset time. For example, when a user parks a vehicle, the target system is in a dormant state, but the user forgets to take something and returns to the vehicle, which will cause the vehicle system to be re-awakened. To avoid the situation where the target system is forced to restart and the user cannot wake up the vehicle, a preset time is set to control the target system to force a cold start after the preset time.

[0083] In a possible implementation, when the target system is in a dormant state, before obtaining the number of hot boots of the target system, a method for determining the number of hot boots of the target system may be:

[0084] When the target system is in an awake state, the number of hot restarts of the target system is determined according to the type of the awake source.

[0085] In this embodiment, different wake-up sources correspond to different startup modes and data processing modes of the target system. When the target system is in the wake-up state, the number of hot startup times of the target system can be determined according to the type of the wake-up source.

[0086] In a possible implementation, according to the type of the wake-up source, a method for determining the number of hot boots of the target system may be:

[0087] When the wakeup source type is target timer wakeup, the number of hot boot times of the target system is cleared to zero.

[0088] In this embodiment, the type of wake-up source is target timer wake-up, which indicates triggering the restart of the target processor. At this time, the restart of the target processor can clear the dynamic storage data corresponding to the target system, thereby clearing the number of hot start times of the target system and restarting the hot start count.

[0089] In a possible implementation, according to the type of the wake-up source, a method for determining the number of hot boots of the target system may be:

[0090] When the startup mode is cold startup and the wakeup source type is non-target timer wakeup and non-network message wakeup, the number of hot startup times of the target system is cleared.

[0091] In this embodiment, when the startup mode is a cold start, and the type of the wake-up source is a non-target timer wake-up and a non-network message wake-up, it is characterized as a forced cold start of the target system automatically triggered by the target system. At this time, the forced cold start of the target system can clear the dynamic storage data and static storage data corresponding to the target system, so that the number of hot starts of the target system can be reset to zero and the hot start count can be restarted. If it is automatically triggered by the target system, it is not used by the user and does not generate storage data, then there is no need to add 1 to the number of hot starts.

[0092] In a possible implementation, according to the type of the wake-up source, a method for determining the number of hot boots of the target system may be:

[0093] When the startup mode is cold startup and the type of the wakeup source is network message wakeup, it is determined that the number of hot startup times of the target system is 1.

[0094] In this embodiment, when the startup mode is cold start and the type of wake-up source is network message wake-up, it is characterized as a forced cold start of the target system that is not automatically triggered by the target system, that is, a forced cold start initiated by the user. At this time, the forced cold start of the target system can clear the dynamic storage data and static storage data corresponding to the target system, so that the number of hot starts of the target system can be reset to zero and the hot start count can be restarted. In addition, for user use, storage data will be generated, and the number of hot starts needs to be increased by 1, that is, the number of hot starts of the target system at this time is 1.

[0095] In a possible implementation, according to the type of the wake-up source, a method for determining the number of hot boots of the target system may be:

[0096] When the startup mode is hot startup and the wakeup source type is non-target timer wakeup and non-network message wakeup, the number of hot startup times of the target system remains unchanged.

[0097] In this embodiment, although the startup mode is hot start, the type of wake-up source is non-target timer wake-up and non-network message wake-up, which is characterized as non-user use. At this time, no storage data will be generated, and the number of hot start times of the target system can be kept unchanged.

[0098] In a possible implementation, according to the type of the wake-up source, a method for determining the number of hot boots of the target system may be:

[0099] When the startup mode is hot startup and the wakeup source type is network message wakeup, the hot startup times of the target system are increased by 1.

[0100] In this embodiment, the startup mode is hot startup, and the type of wakeup source is network message wakeup, which is characterized as a hot startup used by the user, and storage data will be generated, and the hot startup count of the target system can be increased by 1.

[0101] Figure 5 is a flowchart of another system memory cleaning method according to an exemplary embodiment. Figure 5 As shown, the following steps may be included.

[0102] In step S501, it is determined whether the wakeup source is only the target timer. If the wakeup source is not only the target timer, step S502 is executed. If the wakeup source is only the target timer, step S506 is executed.

[0103] In step S502, it is determined whether it is a cold start. If it is not a cold start, step S503 is executed. If it is a cold start, step S505 is executed.

[0104] In step S503, if the system wakes up normally and is not awakened by a network message, the number of hot starts remains unchanged; if the system wakes up by a network message, the number of hot starts increases by 1.

[0105] In step S504, there is no wake-up source, the system enters the sleep state, and executes step S507.

[0106] In step S505, the number of hot starts is reset to zero, and step S503 is executed.

[0107] In step S506, the target processor is restarted, the number of hot starts is cleared, and step S504 is executed.

[0108] In step S507, it is determined whether the number of hot starts is greater than the first target number and less than the second target number. If so, step S508 is executed; if not, step S509 is executed.

[0109] In step S508, the shutdown delay is determined, and the process returns to step S501.

[0110] In step S509, it is determined whether the number of hot starts is greater than the second target number, and the process returns to step S501.
