Fast Fourier Transform for Image Processing in DirectX* 11

Authored by JOSEPH S. (Intel)
This sample demonstrates an optimized FFT that uses compute shaders and Shared Local Memory (SLM) to improve performance by reducing memory bandwidth.Two FFT techniques are discussed. The first is UAV and operates by ping-ponging data repeatedly between Unordered Access Views (UAVs). SLM (Shared Local Memory) is the second technique and is a more memory-bandwidth-efficient method, showing... Last updated on 02/18/2015 - 13:47
