ABSTRACT:
The present invention relates to a discrete transform calculation device (FFTP). The device has control means (CNTRL) which configure first and second memories (RAM1and RAM2) according to the number of transforms used during a first processing. The device applies in particular to a demodulator which allows management of several Fourier transforms in parallel.
