PARALLEL IMPLEMENTATION OF THE FAST FOURIER-TRANSFORM ON 2 TMS320C25 DIGITAL SIGNAL PROCESSORS

We use two fixed-point TMS320C25 digital signal processors (DSP's) to parallel implement the FFT. The significance of this multiprocessing s ystem is: 1) the number of times block data transfer occurs between th ese two DSP's is minimum, 2) each DSP can independently perform the sa me FFT routine with different data set, and 3) the total computational load is nearly equally distributed to two DSP's. The speed-up of this system over a single sequential processor is close to two.
