Abstract
A configurable fast Fourier transforms (FFT) apparatus to compute radix-2 and non-radix-2 calculations. The configurable FFT apparatus includes a data input, a data output, an interconnect, and a configuration manager. The data input retrieves an input data segment from a memory device. The data output stores processed data to the memory device. The interconnect routes radix FFT signals of multi-type radix configurations from the data input to the data output. The configuration manager dynamically configures the interconnect according to a determination of a current radix configuration.
