嵌入式系统中内存管理中间件的研究与实现

Study and Implementation of Memory Management Middleware for Embedded System

通过对内存管理的分析,提出了一个基于嵌入式系统的内存管理的新方案。该方案解决了在嵌入式系统中对有限的内存资源进行统一分配,为上层频繁申请和释放内存块的应用设计了各自独立的内存区。这样,不仅提高了内存管理的效率,而且很大程度地保证了系统的健壮性,加快了对内存问题的定位和解决,让内存管理得到很好优化。

Via the analysis of the memory management, a memory optimizing scheme tor the embedded system is proposed. The scheme solves the problem of limited memory resource allocation in embedded system. Proprietary memory management areas are set up in order to allot independent memory areas for those application modules which request and release memory blocks frequently. By using this scheme, not only the robustness of the system can be fully assured, but also greatly boost the speed of locating and solving the memory problems. As a result, the task of optimizing memory management can be achieved.
