filter-vhdl-code.rar为滤波器的完整VHDL程序，可用于IIR与FIR滤波器的仿真与验证实现，包括代码综合。使用版本为ISE6.3.

介绍了IIR 滤波器的FPGA 实现方法,给出了 IIR 数字滤波器的时序控制、延时、补码乘法和累加四个模块的设计方法,并用VHDL和FPGA 器件实现了IIR 数字滤波。-Introduction of the IIR filter FPGA implementation method of IIR digital filter timing control, delay, multiplication and accumulation complement the four modules

这是一篇关于带通滤波器的毕业设计论文，涵盖IIR与FIR滤波器的设计！-This is an article on the band-pass filter design graduate thesis, covering IIR and FIR filter design!

that is iir filter design in vhdl and it provides good method in that project designing.
