摘　　要：为了在数字信号处理中获得较好的性能和较低的资源消耗,提出了一种新颖的基于Z变换分析的半并行FIR滤波器设计方法.采用Z变换方法进行DSP算法分析非常简单,可以快速精确地计算出延迟的数目,从而可以选择适宜的滤波器结构.实验结果证明,该方法能够有效用于半并行FIR滤波器的流水线和超频控制分析.Z变换方法同样适用于其他DSP算法的硬件设计实现中.For achieving better performance and less resource consume, a novel semi-parallel FIR filters design method based on Z-transform is presented in this paper. Z-transform method is very simple and feasible to analyze DSP algorithms. The method can fast work out accurate numbers of delay, so designer can select feasible filter structure. The experimental results show that the method is effective in semi-parallel FIR filters pipelines structure and over-frequency controlling analysis. The method also can be applied in analyzing hardware implementation of other DSP algorithms.
