TMS320C66x汇编语言的DSP代码优化技术

DSP Code Optimization Technique Based on TMS320C66xAssembly Language

随着主频的不断增加及多核处理器的出现,DSP运算量也不断地提高,但是从系统集成度的提高和成本角度考虑,仍然需要对C语言代码进行优化以提高效率。介绍了TMS320C66x汇编和流水线技术,阐述了在CCS编译器的实时运行环境下,编程需要注意的有关问题,以及如何利用流水线技术提高DSP的处理效率。

DSP is the popular digital processor,it has a very wide application. With the frequency increasing and the multi-core processor appearing, the computational quantity of DSP is also constantly improving. However, from the viewpoint of improving the system integra- tion and reducing the cost, the system needs to optimize the C language code in order to improve the efficiency. This paper describes the TMS320C66 x assembly and pipelining technology, then introduces the real-time operating environment in CCS compiler, the related problems needing to pay attention in programming,and how to use pipeline technology to improve the efficiency of DSP processing.
