Very Naive MIPS CPU using Clash
In this project, we implement a very naive CPU with a 5-stage pipeline that supports a tiny subset of MIPS instructions. This is of course not a functioning CPU in the real world; its main design purpose is to provide a clear logic and an overview of how a pipelined CPU works. We also hope that this project can behave as another tutorial for the Clash language and shows its power and beauty in hardware design. With the help of Clash, we can largely reduce the complexity to implement our toy CPU.
With the goals beard in mind, we also maintain a book that provides basic knowledge of Verilog HDL, Clash, and the CPU with pipeline: how to implement it and how to handle the hazards. There is another important reason making us feel it necessary to provide this book, that is currently some universities require students to write a CPU as their term projects, however, it seems common that most students are not provided with adequate materials; they do even have the experience to write a sequential logic circuit before. There will be far more problems than they may expect. Hence, by providing a hand-by-hand tutorial in this book, we hope that students learning about microprocessors can have more ease and joy.
