Abstract

In this project, a dedicated microprocessor architecture based on the RISC-V (the fifth generation Reduced Instruction Set Computing) with only 20 instructions for arbitrary-point FFT (Fast Fourier Transform) algorithm has been proposed. Moreover, the corresponding SoC (System-on-Chip) is also built for the expansibility and re-configurability. The methodology of software and hardware co-verification is applied to validate the correctness of the systematic functions by comparing the simulation results between MATLAB, Visual Studio 2019 and VIVADO 2019.1. Finally, the Xilinx Artix-7 (XC7A100TFGG484- 2) FPGA (Field Programmable Gate Array) platform is used for implementation and prototyping of the proposed hardware system, which totally uses 1897 LUTs (Look-Up Tables), 361 FFs (Flip-Flops) and 25 BRAMs (Block Random Access Memory) and consumes 2.016W at 100MHz. The experimental results show that the presented system can realize the FFT algorithm at any point by reconfiguring the parameters of software and expanding the capacity of the memory, and it is suitable for the embedded applications due to the small area and low power consumption.
