摘要

本文提出了一种在TMS320C67X架构上实现多项式近似数学函数的通用方法，该架构具有多个并行执行单元。我们的方法包括颗粒打包、映射和调度，以减少数据依赖开销并充分利用延迟槽。在TMS320C67x上的实验结果表明，我们的方法比C67x库函数的性能提高了70.2%。

Optimized parallel implementation of polynomial approximation math functions on a DSP processor

This paper presents a general method to implement polynomial approximation math functions on TMS320C67X architecture with multiple parallel execution units. Our method consists of grain packing, mapping and scheduling to reduce data dependency overhead and fully utilize delay slots. Experimental results of our method on TMS320C67x have achieved up to 70.2% performance improvement over 'C67x library functions.
