摘要
针对离散Walsh变换(简称DWT)在实时信号处理中具有广泛应用,而其运算速度又受到DSP器件性能限制的情况,进行了DWT的并行性研究及并行性能分析;并在基于并行多处理机平台-TMS320C80的编程基础上,实现了两种并行DWT算法。基于TMS320C80进行的实验表明:所开发的并行DWT算法运行结果与理论分析吻合,该并行算法的速度和精度都得到了保证。
With respect to Discrete Walsh Transformation(DWT) wide application in real-time signal processing while limitation in operation speed of DSP.The article makes DWT parallel research and its parallel performance analysis.Based on muhiprocessor platfoml-TMS320C80 programming structure,the research is carried out to achieve two kinds of parallel DWT algorithms.Several experiments demonstrate the effectiveness of the proposed algorithms.
