通信设备中内存管理优化

通过对内存管理的分析，提出了内存优化算法。该算法解决了通信设备中由于大量消息的发送导致内存管理的问题，建立了用户定义的内存管理区域，设计了新的内存管理队列，根据消息块的大小配置内存结构，并给内存块加保护区域，从而提高了内存资源的使用效率，尽可能地杜绝了内存碎片。

Abstract This paper brings forward an optimizing memory algorithm by analyzing memory management. In communications equipments, memory management problems are often raised by mass message flow. The algorithm puts forward a series of solutions on these problems, including building user-defined memory management zone, designing optimized management queue, configuring memory structures according to the size of messages and providing protections on memory block. This design improves usage efficiency of memory resources and put an end to memory fragmentations as possible.
