I've implemented this algorithm from Microsoft Research for a radix-2 FFT (Stockham auto sort) using OpenCL. I use floating point textures (256 cols X N rows) for input and output in the kernel, because I will need to sample at non-integral points and I thought it better to delegate that to the texture sampling hardware.

Webavoid the addition for radix-2 FFT [7,8] but these methods cannot be used for higher radix FFT. This study presents a new architecture to realize the address generation for radix-4 FFT. The new address generator is composed of counters, barrel shifters, multiplexers and registers, but no addition operation is required. WebApr 25, 2024 · Increasing the radix gives us $\log_4$ for radix4, etc., which increases the calculation complexity on hardware, and in turn decreases the number of operations by ~$25\%$. Radix 2 and 4 are considered the most common, while Radix 8 (~$8\%$ optimization) and up generally demand too complex hardware for too small optimizations.
