摘要
文章提出了一种新的FIR数字滤波器硬件实现结构。这种实现结构,大大减少了乘法器以及累加器等硬件资源的使用。文章对比讨论了两种FIR数字滤波器硬件实现结构所占用硬件资源的差别,指出了新结构的优势;通过MATLAB及EDA工具的仿真,表明在完成FIR数字滤波方面,新的硬件实现结构的功能与传统结构是相同的。
A new realizing structure of FIR digital filter is presented in the paper. The new structure greatly reduces the hardware usage of multiplier and ACC. First, discussion goes on two kinds of FIR hardware structure and thus shows the advantage of the new one presented here; later, with MATLAB and EDA simulation ,it is shown that as the digital filtering ability is concerned, there is no difference between the new structure and the traditional one .
