Introduction

DUMBRV is a small RISC-V processor supporting the base RV32E instruction set and the Zicond and Zbs instructions. The processor is made with several state machines. The goal of DUMBRV is not to be fast, but to be small.

Technical Implementation

This processor uses two SPI memories in two independent SPI ports, one is read-only and another is read-write.
