radix-4,利用cordic算法实现复乘单元

用verilog语言编写的基4FFT，采用CORDIC算法实现的，仿真过，结果很好！-I use verilog language to design a FFT base 4,and use CORDIC arithmetic to achieve this. last , I test it, it looks very good

FPGA结合DSP设计，如FIR、IIR滤波器，CORDIC算法,多重采样率信号处理，FFT,有对应的VHDL/Verilog 代码code-FPGA Combines with DSP, FIR 、IIR Digital Filters,CORDIC,FFT,Adaptive Filters，VHDL/Verilog code
