Hence, in order to arrive at efficient implementations, hardware-sharing is required as in microcoded architectures. In this paper, very efficient application-specific realizations spanning a wide throughput range are proposed for both DFT and FFT algorithms. Novel single-cycle address computations are presented for the FFT to obtain these results. Trade-offs between the architectural alternatives are provided too. These designs have been used as test-vehicles for the architectural strategy in an automated synthesis tool-box tuned towards signal processing applications.
