一个DSP实时多任务调度内核的实现

A Real- time Multi- task Kernal for DSP

本文阐述了一个用于DSP的简洁而实用的实时多任务调度内核的实现方法。DSP由于其架构的特殊性,在任务调度方面与通用微处理器相似却又有所不同。本文所阐述的内核架构是笔者在长期实践中总结出来的一种有效而简洁的架构,代码段少,占用内存量小,且完全由C语言开发,可以很方便的在各种DSP上移植。

The thesis expounded that how to achieve a simple and applied Real- Time multi task kernel for DSP. DSP has its special architecture, so it is different from CPU at task attempting. The kernel architecture in this thesis is summarized by author and is simple and efficient, it saves code segment and has low memory cost, and, as it is completely written by C language, the kernel can be easily repotted between different DSP.
