Ne10 v1.2.0 is released. Now radix-3 and radix-5 are supported in floating point complex FFT. Benchmark data below shows that NEON optimization has significantly improved performance of FFT.
The Ne10 project has been set up to provide a…
Fast Fourier Transformation (FFT) is a powerful tool in signal and image processing. One very valuable optimization technique for this type of algorithm is vectorization. This article discusses the motivation, vectorization techniques and performance…
FFT feature in ProjectNe10
Project Ne10 recently received an updated version of FFT, which is heavily NEON optimized for both ARM v7-A/v8-A AArch32 and v8-A AArch64 and is faster than almost all of the other existing open source FFT implementations…
