摘　　要：TMS320C6000系列DSP提供了多种引导加载方式,文中首先对各种加载方式进行了简单介绍,然后针对目前应用广泛的FLASH加载只能加载一段程序,实现一种功能的问题,提出一个可选择加载方案。通过分析COFF文件的结构,给出了加载文件的生成方法,并结合DMA传输给出了可选择加载的软件设计方法。最后附上了程序流程和部分关键代码。实际应用表明,本文提出的可选择加载方法实现过程简单、通用性强,实现了DSP系统在不同功能间切换。TMS320C6000 DSP provided sevral types of boot configurations which the paper firstly described, considering FLASH boot could only load a program, realize single function, the paper submited an optional boot scheme. Through analyzing structure of COFF file the generation method of boot files were listed. Combining DMA transmission the design method of optional bootload software was proposed, finally program flow chart and some critical code were provided. The practical application indicates that the optional boot method listed on this paper can be easily realized, be used widely and realize fuctional shift of DSP system.
