摘要
针对嵌入式系统内存分配具有高效性、可靠性和实时性等要求,每种嵌入式系统在与之相结合的应用场合下,都使用自己的内存管理方案。在路由器等嵌入式系统中,多线程下的大批量内存的分配速度和大量的内存碎片严重影响着系统的稳定性。该文在当前主流嵌入式系统内存管理方案的基础上,就大批量内存分配的高效性和减少内存碎片,提出了基于多级缓存的快速内存分配方案,并测试得出该内存管理方案性能较好。
The requirement for real-time,reliability,high efficiency,makes lots of embedded system applications using their own memory managing methods.Large quantities of memory allocation from multiply threads seriously affect the stability of the embedded system,such as the routers.In order to resolve the efficiency of the large quantities of memory＇s allocation,this paper gives a memory allocating method with multilevel cache,bases on the mainstream memory allocating methods,and it turns to be better after testing.
