WebJun 1, 2014 · CUFFT - padding/initializing question. I am looking at the Nvidia SDK for the convolution FFT example (for large kernels), I know the theory behind fourier transforms and their FFT implementations (the basics at least), but I can't figure out what the following code does: const int fftH = snapTransformSize (dataH + kernelH - 1); const int fftW ... WebI have a basic overlap save filter that I’ve implemented using cuFFT. My first implementation did a forward fft on a new block of input data, then a simple vector multiply of the …
WebOct 3, 2014 · But, with standard cuFFT, all the above solutions require two separate kernel calls, one for the fftshift and one for the cuFFT execution call. However, with the new cuFFT callback functionality, the above alternative solutions can be embedded in the code as __device__ functions. So, finally I ended up with the below comparison code Web-test: (or no other keys) launch all VkFFT and cuFFT benchmarks So, the command to launch single precision benchmark of VkFFT and cuFFT and save log to output.txt file on …
