1024 点FFT，基于基4蝶形运算,在VC编译通过，可以作为FPGA实现仿真参考-1024-point FFT, radix-4 butterfly operations based in the VC compiler, FPGA emulation can be used as reference

this will give details of fft and ifft implementation in vhdl codes, and then on fpga chip

FFT8+FPGA+verilog.输入：butt8_real0—7、butt8_imag0—7为输入的8位数据的实部和虚部；输出：y0_real~y7_real、y0_imag~y7_imag为8点fft的输出 -FFT8 FPGA verilog.butt8_real0—7、butt8_imag0—7y0_real~y7_real、y0_imag~y7_imag
