Memory management method and device

Abstract

The invention discloses a memory management method and device. In the method, whether free memory resource capacity in a private memory resource pool of a first task satisfies a memory resource allocation request sent by the first task is judged after the memory resource allocation request is received, and if yes, memory resources are acquired from the private memory resource pool of the first task for allocation. The private memory resource pool of the task is created for the one task, when the memory resources are allocated, the memory resources are preferentially acquired from the private memory resource pool for allocation, and resource conflict among private memory resource pools and a shared memory resource pool of different tasks will not exist, thus the resource conflict can also be avoided without the need for using a memory mutex in a case where the allocated resources are from the private memory resource pool, and therefore, compared with the prior art, the method reduces use of the memory mutex.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a memory management method and device. Background technique [0002] With the rapid development of multi-core processors, a software parallel processing architecture based on Symmetric Multi-Processing (SMP) has been gradually popularized and applied. In an SMP system, concurrent execution performance directly affects the overall performance of the system, and frequent memory application and release and memory-based message communication are key factors affecting performance in large-scale software. Therefore, how to effectively improve the memory management efficiency under the SMP system has become a important question. [0003] In existing memory resource management schemes, memory blocks are managed in the form of a linked list. If multiple tasks operate on a linked list at the same time, mutual exclusion operations are required to avoid resource conflicts. Among the...

However, the mutual exclusion operation will cause the tasks that cannot obtain the memory mutex to enter the blocked state, thus affecting the concurrent processing efficiency of the system
