# Project-Fetchie | ||
My attempt to make a superscalar RISC CPU | ||
Small 3-stage superscalar RV32I CPU. As of now this is nothing more than a personal pet project. I'm learning as I go, so things might not be right, convensional, clear or efficient to begin with. | ||
|
||
Progress (Checkmark means I have something working, not that it's done): | ||
* Registers ✅ | ||
* I-Cache ✅ | ||
* Fetch ✅ | ||
* Decode | ||
* Execute | ||
* D-Cache | ||
* Microcode + Compiler | ||
|
||
Future extensions: | ||
* Two-level branch prediction | ||
* Debug interface | ||
* Instruction merging (e.g. LUI + ADDI) | ||
* RV32M instructions for multiplication and division | ||
* RV32C instructions for compressed instructions | ||
* RV32E variant of Fetchie for embedded applications |
