Abstract :
This paper proposes a flexible architecture for the FFT and Viterbi algorithms based on the Common Operator (CO) technique. The FFT and Viterbi structural similarities are investigated to build a common architecture for both algorithms where area is traded against throughput. FPGA implementation and experimental results are discussed in this paper.
