The GPro 3 (Ranger) is the third generation of RISC-V processors designed by Gerber Prototyping. Ranger is planned to add a 5-stage pipeline to previous generations. This processor planned for the future.
- RV32IM instruction set
- Modified-Harvard architecture
- 4k instruction and data caches
- Machine-mode and User-mode
- 5-stage pipeline
- data forwarding
- speculative execution
- Low-overhead exception handling
The pipeline design can be found in docs/Pipeline.md.
