A method for the generation of addresses of successive pairs of input data values of stages of a Fast Fourier Transform calculation stored contiguously in a memory includes initializing at most once per stage a first base address pointer to an address of a first input data value of an initial butterfly calculation of the stage and a second base address pointer to an address of a second input data value of the initial butterfly calculation, and initializing at most once per stage a first constant and a second constant. Pairs of input data values of successive butterfly calculations in the stage are then addressed using the first base address pointer, the second base address pointer, the first constant and the second constant.
