摘　　要：因VxWorks自身提供的内存管理函数采用first-fit算法,不能满足通信应用领域软件对内存管理的高实时性和内存利用率的要求,为了解决该问题,基于VxWorks软件开发平台给出新的内存管理实现方法:采用两套完全独立的内存池集——进程通信内存池集和应用内存池集,平台直接管理内存,为整个系统提供高效的动态内存管理机制,使新定义的内存管理模块更适合通信产品应用领域的嵌入式软件开发.As the memory management functions self-offered by VxWorks which use first fit algorithm can not satisfy the demands of strict timeliness and efficiency of memory management in the communication applications of software, to solve the problem, a new realizing method of memory management was advanced for the software development platform based on VxWorks using two completely independent memory pool sets-one for process communication, and the other for the applications, with the platform directly managing the memory, and providing the high efficient dynamic memory management mechanism for the whole system. The newly defined memory management module is more suitable for the development of embedded software in the applica- tion of communication products.
