Abstract
Various embodiments of the present technology may comprise a method and apparatus for in-place fast Fourier transform (FFT). According to various embodiments, the apparatus comprises a RAM, having a single address space, divided into a plurality of sub-memory spaces, where the number of sub-memory spaces is a function of a length of the FFT such that the two inputs are always from different sub-memories, as are the two outputs. According to various embodiments, the apparatus may further comprise a division circuit configured to perform a 'bitwise' division operation in order to convert addresses from the aforementioned single address space to the particular sub-memories and addresses within them. According to various embodiments, the apparatus may further comprise a butterfly processor capable of performing a butterfly operation.
