TS20XS系列DSP程序优化设计方法及应用

摘要

TS2OXS series DSP is a high performance digital signal processor^[7]. The demand for real time perform- ance of the algorithm is increasing in engineering implementation, so hardware resources of DSP and programming languages should be used reasonably to reduce instruction execution cycle and improve the executive efficiency of the algorithm. Several optimal design methods of the DSP program are discussed in the aspects of usage of double-group ~gister, use of IF-DO-ELSE instruction, the proper distribution of coefficients storage units, shortening of time-lag between instructions and reasonable use of dual integer arithmetic logic unit. Some optimal design results are given.%TS20XS系列DSP是一款高性能数字信号处理器＾［7］。由于在实际工程中对算法的实时性要求越来越高，所以要合理使用DSP的硬件资源和编程语言，进而减少指令的执行周期，提高算法的运行效率。．本文分别从TS20XS系列DSP两组寄存器组的使用、IF—DO—ELsE指令的使用、系数存储单元的合理分配、指令间延时的减少、双整型逻辑运算单元的综合运用这几方面探讨了DSP程序的优化设计方法，并结合实例给出优化设计结果。
