Abstract
A method for processing data based on 3072-point Fast Fourier Transform (FFT) and a processor based on 3072-point FFT are provided. The method for processing data based on 3072-point FFT includes: storing 3072-point data into a data storage module according to a predetermined mapping relationship (101); reading 16 data in parallel from the data storage module for performing 3-point DFT operation, and storing results into the data storage module in situ after completion of the operation (102); and reading 32 data in parallel from the data storage module for performing 1024-point DFT operation and storing results into the data storage module in situ after completion of the operation until the FFT of 3072-point data is completed (103).
