摘要
针对离散Walsh变换(DWT)在实时信号处理中具有广泛应用,而其运算速度受到DSP器件性能限制的实际情况,进行了离散Walsh变换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的编程结构基础上,实现了并行离散Walsh变换。在TMS320C80进行的试验表明:所开发的并行DWT算法运行结果与理论分析是吻合的,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 and limitation in operation speed of DSP, the article makes DWT parallel research and its parallel performance analysis. Based on multiprocessor platform - TMS320C80 programming structure, research is carried out to achieve DWT. Several experiments demonstrated the effectiveness of the proposed algorithm.
