This a vhdl code written to compute fft for the values stored in a RAM. The fft values are stored in bit reversed order finally in the same RAM. Not sure if it is working 100 . For my test input it worked.-This is a vhdl code written to compute fft for the values stored in a RAM. The fft values are stored in bit reversed order finally in the same RAM.
