bit reverse

dan over 8 years ago

I was hoping that there would be some psuedo or example code for the CMSIS generated bit reverse look up tables for the FFTs. I would like to try and extend the FFT to 8k in length. So I am looking at these tables, but can not figure out how they are generated, specifically the tables like armBitRevIndexTable128.

Thanks.

Thanks for the input all. Time line is short, so I adjusted my path and have decomposed the FFT into smaller FFTs to generate the needed 8k FFT. Likely not the most optimal solution, but meets the requirements.
For those interested in the algorithm...
