Overall, the big prime field FFT on the GPU is the best approach. A discrete Fourier transform (DFT) over Z⇑pZ, when p is a gen-eralized Fermat prime, can be seen as a generalization of the FNT

The FFT on a GPU - Kenneth Moreland

WebGPU-enabled functions run on the GPU only when the input data is on the GPU. The data type of parameter arguments such as dimensions or indices do not affect where the function is run. For example, the sum function in this code runs on the GPU because the data, the first input, is on the GPU. A = rand (10); d = 2; sum (gpuArray (A),d); Web本发明提供一种基2‑fft的并行gpu检测算法，主要为大型图像的检测提供快速计算方案。本方法将原有的fft蝶形算法3层循环做以下处理：最外层循环做串行计算，内部2层循环用公式统一后做并行计算。最外层循环次数是计算量的对数，类似于二叉树的深度，所以外层串行计算 … chef wagner
