Abstract :
In this paper, we present the mapping of Radix-2 and Radix-4 FFT algorithms using CREMA, a Coarse-Grain Reconfigurable Array (CGRA) with mapping adaptiveness. CREMA is employed to generate special purpose accelerators tailored on the specified mapping. We analyze the results for 64-point FFT targeted for OFDM processing. Both of the implementations are (4–5X) smaller and showed a speed-up of 4X when compared with a general-purpose CGRA.
