Abstract
We present a new formulation of fast Fourier transformation (FFT) kern els for radix 2, 3, 4, and 5, which have a perfect balance of multipli es and adds. These kernels give higher performance on machines that ha ve a single multiply-add (mult-add) instruction. We demonstrate the su periority of this new kernel on IBM and SGI workstations.
