Floating Point Implementation of FFT Using a Novel ESL Design Flow

To demonstrate the benefit of Electronic System Level (ESL) methodology, the development of scalar and parallel FFT engine is presented using a novel ESL design flow in this paper. A novel design flow was detailed firstly. In this design flow, a 32-bit IEEE-754 datapath was implemented. A parallelizing technique is also presented to utilize the inherent parallelism in the algorithm. According to the importance of the FFT algorithm, scalar and parallel FFT engines are developed using this design flow to demonstrate the benefit of ESL methodolog.
