Abstract
Twiddle factor generation for use with a programmable mix-radix vector processor ('PVP') capable of calculating discrete Fourier transform ('DFT/IDFT') values. In an exemplary embodiment, an apparatus includes look-up table logic that receives twiddle control factors and outputs a selected twiddle factor scaler value (TFSV), a base vector generator that generates a base vector values based on the selected TFSV, and a twiddle column generator that generates a twiddle vector from the base vector.
