摘　　要：Nucleus PLUS是一种嵌入式实时操作系统内核,其内存管理采用实存储器管理技术。本文详细研究了Nucleus PLUS动态内存管理机制及实现细节,针对主要系统函数介绍测试思路及测试用例设计方法。最后从内存碎片和内存越界风险两个角度对该内存管理机制进行评估,提出改进措施和内存越界检测方法。为基于本版本Nucleus PLUS的嵌入式开发在动态内存使用方面提供参考和指导。Nucleus PLUS is the kernel of an embedded real-time operating system,and it uses real memory management technology.The dynamic memory management mechanism and the specifics of its realization are studied in the paper.The testing ideas and test-case design for the most primary functions are introduced.The memory management mechanism is introduced from the two perspectives:the memory fragments and the memory overrun,and the improvement measures and the method of memory transboundary detection are put forward.It provides the reference and guidance for the use of dynamic memory during embedded development based on this operating system.
