<p>A processor and processing method for FFT/IFFT are provided. The processor includes: a control signal and address signal generator (102), which is configured to generate the control signal and the address signal; a random access memory module (104), which is configured to store input data and intermediate calculating results; a read-only memory module (106), which is configured to store twiddle factors; a data processing module (108), which is configured to implement butterfly operations on the input data according to the control signal and the twiddle factor, and then to transmit the intermediate calculating result back to the random access memory module to store. The invention can realize IFFT/FFT transforms compatible with any even point whose length is longer than or equal to four.</p> |
