Design of a Cordic Based Radix-4 FFT Processor
The digital signal processing has been dominated by microprocessors with enhancements such as special addressing modes and single cycle multiply-accumulate instructions. While these processors offer extreme flexibility with low cost, they are often not fast enough for most of DSP tasks. The arrival of reconfigurable logic computers offers hardware solutions for higher speeds at costs which are less than traditional software approach. Unfortunately, algorithms used for these micro-processor based systems cannot be mapped into hardware.
