Full Open-Source Implementation of an Academic RISC-V on FPGA

In alignment with the ethos of openness and democracy inherent in the RISC-V architecture, our research endeavors have been directed towards the utilization of open-source tools for the implementation of a simple but didactic RISC-V processor denoted as ASTIRV32I. The paper discusses the design strategies, memory mapping, physical verification procedures, and performance evaluation of the ASTIRV32I processor. Furthermore, it highlights the successful validation of the implemented design through the execution of fundamental algorithms, exemplifying the practicality and viability of the RISC-V-based processor design and serving as a proof-of-concept for open-source FPGA design.
