Abstract :
The author presents an analysis of the cost-effectiveness of discrete Fourier transform processors, based on CORDIC modules such as the bit-serial, parallel with non-redundant and redundant arithmetic, and pipelined. The performance of each processor is analyzed with respect to the time to process one frequency output and the number of modules required. It is shown that the CORDIC-based DFT processor is a prospective solution in VLSI to be used for a wide range of input bit rate
