Abstract
An FFT device for performing a Fast Fourier Transform (FFT) is described. The FFT device comprises: a control unit arranged to control a sequence of transformation rounds; and a coefficient unit for providing transformation data; and a transformation unit arranged to receive the transformation data and to perform the respective linear transformation on the basis of the transformation data. The coefficient unit comprises or is integrated in a Random Access Memory (RAM) unit, the RAM unit comprising a set of memory blocks. The set of memory blocks comprises: a subset of window memory blocks or a subset of window-FFT memory blocks. The set of memory blocks further comprises a subset of FFT memory blocks providing a set of twiddle coefficients or a reduced set of twiddle coefficients.
