Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to data processing technology, and particularly relate to a memory dynamic management method, device, equipment and storage medium. BACKGROUND

[0002] In a computer system, memory is one of the most important resources. Its capacity directly affects the overall performance of the system. Assuming that multiple services need to be performed at the same time, one service is responsible for producing data, and the remaining services consume data, since there are multiple services consuming data, a buffer needs to be created, which is also called shared memory.

[0003] In multi-thread programming, the traditional data sharing method is to read and write data on a block of memory by using a locking method to allow multiple services to read and write data on the block of memory. The reading position of each thread is different, and the writing position needs to be in front of the reading position. When the buffer is full, the number of rounds needs to be recorded and compared with the number of reading rounds. However, after the number of services increases, the method of sharing a block of memory is not efficient, is prone to deadlocks, and the use efficiency of the memory cannot be optimized. SUMMARY

[0004] The present application provides a memory dynamic management method, device, equipment and storage medium to dynamically monitor the memory usage of each task, dynamically manage the memory, and optimize the use efficiency of the memory.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0034] Example 1

[0035] Figure 1 This is a flowchart illustrating a dynamic memory management method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where multiple tasks need to use shared memory, and the method can be executed by a dynamic memory management device.

[0036] As shown in the figure, a dynamic memory management method specifically includes the following steps:

[0037] Step 110: Create a corresponding number of memory regions according to the number of preset tasks, and allocate memory to each memory region according to the preset memory value.

[0038] When multiple tasks need to use data generated by the same business process, i.e., when shared memory is required, a corresponding number of memory regions are created based on the number of preset tasks. Memory is allocated to each of these memory regions according to a preset memory value, and the generated data is cached in the memory regions corresponding to each preset task. Each task only needs to retrieve data from its own corresponding memory region without needing to interact with other modules, thus improving the speed and accuracy of data retrieval and caching for each task. When creating the memory region corresponding to each preset task, memory is allocated to each region according to a preset memory value, initially allocating the same amount of memory. In practical applications, considering that actual embedded memory space is limited, MEM_CONSUMERS_MAX is used to limit the size of the shared memory.

[0039] Furthermore, after a memory region is allocated a preset memory, there is a certain difference between the actual allocated memory and the allocated memory. The actual allocated memory (MemTotal) is determined by the preset memory value and a preset valid range, NiceRange(nice_min, nice_max), where nice_min and nice_max are decimals greater than 0 and less than 1. The preset valid range is determined by the preset memory value and a valid threshold. The minimum value of the preset valid range is the product of the preset memory value and the minimum value of the valid range, and the maximum value of the preset valid range is the product of the preset memory value and the maximum value of the valid range. Therefore, the minimum value of a memory allocation's preset valid range is NiceMin = MemTotal * nice_min; the maximum value of a memory allocation's preset valid range is NiceMax = MemTotal * nice_max.

[0040] Step 120: At preset time intervals, repeatedly obtain the used memory value of each memory region.

[0041] Each task's execution is significantly affected by other factors, and the speed of memory access may vary. The memory usage of each task's corresponding memory region differs at different times. Therefore, to dynamically manage each memory region and achieve optimal memory utilization, the used memory value of each memory region is retrieved cyclically at preset time intervals. The preset time interval is a unit of time, such as 1 second.

[0042] Prior to step 120, the process also includes: creating a monitoring thread to monitor the used memory value of each of the memory regions.

[0043] Create a monitoring thread to monitor the used memory value of each memory region, specifically to monitor the memory data used and the remaining memory size of the memory region corresponding to each task within a unit of time.

[0044] Step 130: Determine whether the used memory value is within a preset valid range.

[0045] The amount of cached data required for each task may not be the same, and the amount of memory used in the memory area corresponding to different tasks may also be different. Some tasks use less memory and the initially allocated memory is not fully utilized, while some tasks use more memory and the initially allocated memory may not be enough. In order to improve memory usage efficiency, it is necessary to determine the memory usage of each task.

[0046] The determination of whether the used memory value is within a preset valid range includes determining whether the used memory value is greater than the maximum value of the valid range and determining whether the used memory value is less than the minimum value of the valid range.

[0047] When the used memory value (MemUsed) of a task's memory region is consistently less than the minimum effective range value (NiceMin), it indicates that the task has a relatively large amount of memory remaining, and the currently allocated memory can be appropriately reduced. When the used memory value (MemUsed) of a task's memory region is consistently greater than the maximum effective range value (NiceMax), it indicates that the task has a relatively small amount of memory remaining, and the currently allocated memory can be appropriately increased. When the used memory value of a task's memory region is between the minimum and maximum effective range values, it indicates that the memory usage of the task is normal and no adjustment is needed. In this case, return to step 120.

[0048] Step 140: Dynamically manage the memory of the memory region based on the used memory value and effective coefficient of the memory region.

[0049] Based on the used memory value of the memory region, reduce the region with more remaining memory and increase the region with less remaining memory.

[0050] Step 140 includes:

[0051] Step 141: Calculate the newly allocated memory value based on the used memory value of the memory region and the minimum value of the effective range.

[0052] Step 142: Reallocate memory in the corresponding memory region according to the newly allocated memory value.

[0053] The formula for calculating the newly allocated memory value (NewMem) is: NewMem = MemUsed / nice_min, which is calculated by dividing the used memory value by the minimum effective range, ensuring that the used memory value is within the effective range of the reallocated memory value.

[0054] Furthermore, after memory is reallocated, the monitoring thread continues to monitor the memory usage of the memory regions corresponding to each task, and adjusts the memory allocation in a loop according to the memory usage, thereby achieving the effect of dynamic memory allocation.

[0055] For example, three preset tasks correspond to three memory regions, each allocated a preset memory value, such as 200M for each region, with an effective range of NiceRange(0.8, 0.9) and a preset effective range of [160, 180]. Q1, Q2, and Q3 represent the memory allocation of the three tasks. After running for a period of time t1, the first task's memory Q1 only uses 100M, leaving 100M of memory. Since the used memory is less than the minimum value of the preset effective range, memory allocation can be reduced, with a new allocated memory value NewMem = 100 / 0.8 = 125. The second task's memory Q2 uses 200M, leaving no memory. Since the used memory is greater than the maximum value of the preset effective range, memory allocation needs to be increased, with a new allocated memory value NewMem = 200 / 0.8 = 250. The third task's memory Q3 uses 170M, which is within the preset effective range, and no memory adjustment is needed. After adjustment, the effective range of memory Q1 for the first task is [125*0.8, 125*0.9], which is [100, 112]; the effective range of memory Q2 for the second task is [250*0.8, 250*0.9], which is [200, 225]. After time t2, the actual memory usage of Q1 for the first task is 115M, exceeding the effective range, requiring additional memory. The newly allocated memory value NewMem = 115 / 0.8 = 143; the actual memory usage of Q2 for the second task is 210M, within the effective range, and tending to stabilize, requiring no further adjustment; Q3 remains stable and requires no adjustment. After two memory adjustments, the memory allocation of the memory regions for the second and third tasks tends to stabilize. Continued monitoring and adjustment of the memory allocation for the first task's memory region are still needed. After memory reallocation, the monitoring thread continues to monitor memory usage, running in a loop to achieve dynamic memory allocation and optimize memory utilization.

[0056] Furthermore, step 142 also includes: reallocating the memory of the memory region according to the priority order of preset tasks.

[0057] The priorities of each task may differ. Priority order can be set for each task. According to real-time requirements, memory can be dynamically managed first for high-priority tasks to meet the memory allocation needs of urgent tasks and improve the efficiency of task execution.

[0058] Furthermore, it also includes: reclaiming the memory space corresponding to the preset tasks that have been completed.

[0059] In embedded systems, multiple tasks do not necessarily exist simultaneously. When a task needs data from the producer, shared memory can be dynamically created. When it is no longer needed, the shared memory can also be dynamically released, so that the system's memory space can be used efficiently.

[0060] When a task has been completed, it can be dynamically destroyed to prevent it from consuming too much memory, and the corresponding memory space can be reclaimed and dynamically allocated to improve memory usage efficiency.

[0061] The technical solution of this embodiment provides a dynamic memory management method, including: creating a corresponding number of memory regions based on the number of preset tasks; allocating memory to each memory region according to a preset memory value; cyclically acquiring the used memory value of each memory region at preset time intervals; determining whether the used memory value is within a preset valid range; and dynamically managing the memory of the memory regions based on the used memory value and a valid coefficient. By cyclically acquiring the used memory value of each task and comparing it with the preset valid range, the memory corresponding to tasks with more remaining memory is reduced, while the memory corresponding to tasks with less or insufficient remaining memory is increased. This ensures that each task has adequate memory during execution, addressing the problem of low efficiency and potential deadlocks when sharing memory when there are many tasks. Dynamic management based on the memory usage value of each task at different times improves memory utilization efficiency. In multi-tasking scenarios, dynamic memory management optimizes memory utilization and avoids deadlocks.

[0062] Example 2

[0063] Figure 2 This is a schematic diagram of the structure of a memory dynamic management device provided in an embodiment of the present invention.

[0064] like Figure 2 As shown, a memory dynamic management device includes:

[0065] The initial memory allocation module 210 is used to create a corresponding number of memory regions according to the number of preset tasks, and allocate memory to each memory region according to the preset memory value.

[0066] When multiple tasks need to use data generated by the same business process, i.e., when shared memory is required, a corresponding number of memory regions are created based on the number of preset tasks. Memory is allocated to each of these memory regions according to a preset memory value, and the generated data is cached in the memory regions corresponding to each preset task. Each task only needs to retrieve data from its own corresponding memory region without needing to interact with other modules, thus improving the speed and accuracy of data retrieval and caching for each task. When creating the memory region corresponding to each preset task, memory is allocated to each region according to a preset memory value, initially allocating the same amount of memory. In practical applications, considering that actual embedded memory space is limited, MEM_CONSUMERS_MAX is used to limit the size of the shared memory.

[0067] Furthermore, after a memory region is allocated a preset memory, there is a certain difference between the actual allocated memory and the allocated memory. The actual allocated memory (MemTotal) is determined by the preset memory value and a preset valid range, NiceRange(nice_min, nice_max), where nice_min and nice_max are decimals greater than 0 and less than 1. The preset valid range is determined by the preset memory value and a valid threshold. The minimum value of the preset valid range is the product of the preset memory value and the minimum value of the valid range, and the maximum value of the preset valid range is the product of the preset memory value and the maximum value of the valid range. Therefore, the minimum value of a memory allocation's preset valid range is NiceMin = MemTotal * nice_min; the maximum value of a memory allocation's preset valid range is NiceMax = MemTotal * nice_max.

[0068] The memory dynamic monitoring module 220 is used to cyclically acquire the used memory value of each memory region at preset time intervals.

[0069] Each task's execution is significantly affected by other factors, and the speed of memory access may vary. The memory usage of each task's corresponding memory region differs at different times. Therefore, to dynamically manage each memory region and achieve optimal memory utilization, the used memory value of each memory region is retrieved cyclically at preset time intervals. The preset time interval is a unit of time, such as 1 second.

[0070] Optionally, a memory dynamic management device may further include: a thread creation monitoring module;

[0071] The monitoring thread creation module is used to create monitoring threads to monitor the used memory value of each of the memory regions.

[0072] Create a monitoring thread to monitor the used memory value of each memory region, specifically to monitor the memory data used and the remaining memory size of the memory region corresponding to each task within a unit of time.

[0073] The memory usage determination module 230 is used to determine whether the used memory value is within a preset valid range.

[0074] The amount of cached data required for each task may not be the same, and the amount of memory used in the memory area corresponding to different tasks may also be different. Some tasks use less memory and the initially allocated memory is not fully utilized, while some tasks use more memory and the initially allocated memory may not be enough. In order to improve memory usage efficiency, it is necessary to determine the memory usage of each task.

[0075] The determination of whether the used memory value is within a preset valid range includes determining whether the used memory value is greater than the maximum value of the valid range and determining whether the used memory value is less than the minimum value of the valid range.

[0076] The dynamic management module 240 is used to dynamically manage the memory value of the memory region based on the used memory value and the effective coefficient of the memory region.

[0077] Based on the used memory value of the memory region, reduce the memory value of tasks with more remaining memory and increase the memory value of tasks with less remaining memory.

[0078] Dynamic management module 240 includes:

[0079] The newly allocated memory value calculation unit is used to calculate the newly allocated memory value based on the used memory value of the memory region and the minimum value of the effective range.

[0080] The memory management unit is used to reallocate memory in the corresponding memory region according to the newly allocated memory value.

[0081] The formula for calculating the newly allocated memory value (NewMem) is: NewMem = MemUsed / nice_min, which is calculated by dividing the used memory value by the minimum effective range, ensuring that the used memory value is within the effective range of the reallocated memory value.

[0082] After memory is reallocated, the monitoring thread continues to monitor the memory usage of the memory regions corresponding to each task, and adjusts the memory allocation in a loop according to the memory usage, thereby achieving the effect of dynamic memory allocation.

[0083] Optionally, the memory management unit includes a sequential management subunit, used to reallocate the memory of the memory region according to the priority order of preset tasks.

[0084] The priorities of each task may differ. Priority order can be set for each task. According to real-time requirements, memory can be dynamically managed first for high-priority tasks to meet the memory allocation needs of urgent tasks and improve the efficiency of task execution.

[0085] Optionally, the memory dynamic management device may also include: a reclamation and allocation module;

[0086] The recycling and allocation module is used to reclaim the memory space corresponding to the preset tasks that have been completed.

[0087] When a task has been completed, it can be dynamically destroyed to prevent it from consuming too much memory, and the corresponding memory space can be reclaimed and dynamically allocated to improve memory usage efficiency.

[0088] The technical solution of this embodiment provides a dynamic memory management method, including: creating a corresponding number of memory regions based on the number of preset tasks; allocating memory to each memory region according to a preset memory value; cyclically acquiring the used memory value of each memory region at preset time intervals; determining whether the used memory value is within a preset valid range; and dynamically managing the memory of the memory regions based on the used memory value and a valid coefficient. By cyclically acquiring the used memory value of each task and comparing it with the preset valid range, the memory corresponding to tasks with more remaining memory is reduced, while the memory corresponding to tasks with less or insufficient remaining memory is increased. This ensures that each task has adequate memory during execution, addressing the problem of low efficiency and potential deadlocks when sharing memory when there are many tasks. Dynamic management based on the memory usage value of each task at different times improves memory utilization efficiency. In multi-tasking scenarios, dynamic memory management optimizes memory utilization and avoids deadlocks.
