嵌入式实时动态内存管理机制研究与应用

Research and Application of Embedded Real-Time Dynamic Memory Management Mechanism

针对长时间持续运行的通信设备必须满足实时性、可靠性和高效性需求的特点,提出并实现了一种新方案.该方案可对嵌入式系统有限的内存资源进行统一再分配,为频繁申请和释放内存块的应用分配独立的内存空间,不仅可提高动态内存管理的实时性,减少内存碎片,保证系统的健壮性,而且提供了内存越界和内存泄漏检测手段.

The communication equipments which mn continuously in a long time must be real-time, reliability and efficiency. For these features in communications, this paper proposes and implements a new mechanism, which can do a unified redistribution with the limited memory resources in embedded systems. This mechanism distributes an independent memory space for applications which allocate and free memory frequently, which can not only improve the dynamic memory management efficiency, reduce memory flagments, ensure the robustness of the system, but also provide a method for detecting memory overrun and memory leak.
