Read address for fft

[achaleus]

Hello everyone, I am doing project on 1024 point implementation of FFT on FPGA(RADIX 2). how to generate address to read the data stored in RAM blocks at each stage, I tried bit reversal logic but grouping is correct but order is different. Please help.


thanks in advance,
Vinay Kumar Maddal.
