Multi-cycle processor RISC-V with RV32E implementation, developed during some days off, optimizated to TinyTapeout.
The official language adopted by the project is Brazilian Portuguese; therefore, most of the documentation and commits are in this language.
The processor was implemented using Verilog HDL and features a multi-cycle implementation without pipelining.
The software directory contains examples and tests written in Assembly, along with their respective memory files. Additionally, there's a script available to convert Assembly code into memory files. The official processor firmware is also available in the software/firmware directory.
The tests directory includes various tests built using Iverilog. All tests in this directory are compatible with Iverilog.
