## What it is
Ripes is a graphical processor simulator and assembly editor for the RISC-V ISA, built with Qt. It visualizes how machine code executes on RV32/RV64 microarchitectures, including cache behavior and memory-mapped I/O.

## Use cases
- visualize how RISC-V machine code executes on a pipelined processor
- learn computer architecture concepts like cache design and performance
- assemble and simulate RISC-V assembly code step by step
- explore how C code compiles down to RISC-V machine code
- simulate memory-mapped I/O interaction with a processor
- teach a computer architecture course with a visual CPU simulator

## When to choose
- you need a visual, interactive way to learn or teach RISC-V processor internals
- you want to compare cache designs and their performance impact
- you need a cross-platform or in-browser RISC-V assembly simulator

## When to avoid
- you need a fast, scriptable RISC-V emulator for running real software
- you require cycle-accurate simulation of a specific commercial processor
- you need a headless or CLI-only simulation environment

## Facets
- artifact type: application
- maturity: active
- function: simulation, gui, editor
- domain: education, developer-tools
- platform: windows, browser, wasm
- tags: risc-v, cpu-simulator, assembly-editor, qt, cache-simulation, microarchitecture, education, computer-architecture, linux, macos
