串并FIR滤波器设计:并行FIR滤波器具有速度快、容易设计的特点,但是要占用大量的资源。在多阶数的亚高频系统设计中,使用并行结构并不合算,但亚高频系统需要较高的处理速度,而串行架构往往达不到要求,因此,结合串并这两种设计方法的长处,在使用较少的硬件资源的同时实现了较高的处理速度,这里说明一种65阶八路并行、支路串行FIR滤波器的设计(实际使用了1个乘法器,8个乘累加器,一个累加器)。-String and FIR filter design: parallel FIR filter with a

RobustVerilog generic FIR filter
In order to create the Verilog design use the run.sh scr ipt in the run directory (notice that the run scr ipts calls the robust binary (RobustVerilog parser)).
The filter can be built according to 3 differe

一个VHDL编的简单乘法器,基本原理设计如下图所示: 将两个操作数分别以串行和并行模式输入到乘法器的输入端, 用串行输入操作数的每一位依次去乘并行输入的操作数, 每次的结果称之为部分积, 将每次相乘得到的部分积加到累加器里, 形成部分和, 部分和在与下一个部分积相加前要进行移位操作。-A simple multiplier VHDL series, the basic principles of design as follows: two operands, respectively, ser

Multiplication is performed in three stages. After reset, the 8-bit operands are “loaded” and the product register is set to zero. In the second stage, s1, the actual serial-parallel multiplication takes place. In the third step, s2, the product is t
