Abstract
A system for implementing a mixed radix fast fourier transformation is disclosed. The system includes a data source, a digit-reverse address generator, a data memory, a register array, a control unit, a butterfly extraction unit, a twiddle factor generator, and a computation unit. The data sourceprovides input data. The digit reverse address generatorprocesses the input data (i) to generate a digit reverse index and performs a digits reverse address calculation. The data memorystores the input data. The register arrayincludes one or more registers that are configured to cache multiple data words. The control unitincludes of identifying butterfly operations and generate addresses for fetching/storing data. The butterfly extraction unitextracts data samples. The twiddle factor generatorgenerates and outputs a twiddle factors based on the current radix and radix configuration. The computation unitperforms twiddle factor multiplications and the butterfly operations for current radix.
