This paper discusses different approaches for computing the Walsh spectra on graphics processor unite (GPU) using CUDA C. Here we present the results from several experiments that evaluate the performance of NVIDIA processors, implementing on two GPU with different performances. The conclusions from experiments made indicate what speed-ups can be expected, when instead of standard CPUs, accelerators in the form of presented GPUs are used, for considered computational kernels.
