摘　　要：主要研究了操作系统中利用位示图进行存储分配和回收的基本理论。详细介绍了用位示图实现存储资源分配的算法流程和二级位示图目录的有关概念,并推广到多级位示图目录法。对位示图分配方式的管理开销进行了分析与探讨。The article mainly focuses on the theories of working process and concepts of using bitmap to allocate and recall memory in operating system.A detailed description of algorithms flow chart is given, which is about a memory resorce allocation using bitmap. This article also dis cusses the concept of a 2-level bitmap catalogue method and extends multilevel bitmap catalogue. In the meantime, it studies and analyzes managing overhead of memory management based on bitmap.
