Implementation and Evaluation of two 32-Point Butterfly FFT Accelerators in a RISC-V Core
This project integrates two 32-point Fast FourierTransform (FFT) accelerators into the RS5 RISC-V processor, afour-stage pipeline architecture supporting custom instructions.We evaluate two FFT accelerator designs (one with parallelinput/output and another with serial input/output), comparingtheir performance against a...
