Abstract - This paper presents a solution based on
parallel-pipelined architectures for high throughput and power
efficient FFT IP cores. Low power consumption can be gained
through the combination of hybrid low power algorithms and
architectures. A number of IP cores have been implemented for
the comparison of the impact of parameterization on
power/area/speed performance. The results show that up to
55% and 52% power saving can be achieved by the
combination of the above techniques for 64-point
4-parallel-pipelined FFT and 16-point 2-parallel-pipelined FFT
respectively, as compared to R4SDC pipelined FFTs.
I. Introduction
The FFT processor is used in a wide range of DSP and
communication applications, such as radar signal processing
