Ripes is a graphical processor simulator and assembly editor for the RISC-V instruction set architecture.
Ripes addresses the challenge of understanding how processors execute code and how architectural decisions affect performance. It provides a visual environment where users can write or load RISC-V assembly code and observe its execution across different microarchitectures. The tool simulates various processor designs based on RV32IMC and RV64IMC variants, allowing exploration of how cache designs influence performance, how C code compiles to assembly, and how processors interact with memory-mapped I/O.
The tool suits educators and students learning computer architecture, as well as anyone needing to understand RISC-V instruction execution in detail. It works best for projects focused on RISC-V development and education rather than production systems. Ripes is available as native applications for Linux, Windows, and macOS, and also runs directly in a web browser through a WebAssembly deployment, making it accessible without installation.
The project maintains active build pipelines across multiple platforms and deployment targets. The maintainers engage with users through a dedicated discussions page for feature requests and ideas, and actively track bug reports through the issues page. Documentation is provided through an introduction tutorial and comprehensive reference materials.
