A case study exploring multi-frequency design is presented for a low energy and high performance FFT circuit implementation. An FFT architecture with concurrent data stream computation is selected. An asynchronous and synchronous implementations for a 16-point and a 64-point FFT circuit were designed and compared for energy, performance and area. Both versions are structurally similar and are generated using similar ASIC CAD tools and flows. The asynchronous design shows a benefit of 2.4x, 2.4x and 3.2x in terms of area, energy and performance respectively over its synchronous counterpart. The circuit is further compared with other published designs and shows 0.4x, 4.8x and 32.4x benefit with respect to area, energy and performance.
