Abstract :
In this paper, a method of realizing a real time high speed two-dimensional (2-d) FFT processor is proposed. A fully implemented lower order FFT processor block is timeshared to do row/column transforms of a two-dimensional array of complex samples. An efficient method of matrix transposition is also considered. The design details of the processor with commercially available CMOS digital ICs are given. Hardware complexity/power versus speed comparison and computer simulation results are also included.
