Processor simulator written in TypeScript for the DLX architecture. Inspired by WinDLX.
Instructions follow WinDLX format and opcode table.
Info: 🦺 Work in progress. Lots of features are missing. Only integer registers are supported. Forwarding is not yet implemented.
DLX simulator can be used as a command line tool, library or a web application.
Kinda related to the university course on computer architecture. This was not an assignment, just a fun project. Might abandon at any time or never finish.
Could all of that be done in a better way, with less effort or is WinDLX enough? The answer is YES! But c'mon writing own parser, assembler, getting pipeline stalls to work properly, implementing forwarding, creating in-browser unit tests editor to assert on mem and registers values, just sounds fun!
- 🎨 Tired of Windows XP look? New, modern UI!
- :www: No need to install, run directly within the browser (asynchronously in a WebWorker)!
- 🔠 Support for WinDLX instructions
- 💅 Syntax highlighting? Oh yeah, we've got that. No more NotePad++ within a VM.
- 📊 Real-time pipeline visualization
- 💾 Register and memory inspection interface
- ✔️ Write tests in JavaScript for program correctness
chai.jsassertions on register/memory values- I'm sorry, I think it's pretty cool
- 📃 Detailed, logs
- 1️⃣ DLX assembly language assembler, including tokenizer, lexer and parser
- 🔍 TODO: Profiler
- Implement pipeline
- Implement basic pipeline
- Implement stalls (WIP)
- Implement forwarding
- Implement int registers
- Implement basic immediate arithmetic instructions and
sw,lw - Implement memory preloading
- Implement all instructions
- Implement floating point instructions/registers
- Implement double precision instructions/registers
- Implement jumps
- Implement profiler
Library is written in TypeScript. The only runtime dependency is nanoevents package which contains isomorphic event emitter.
pnpm tsx repl/repl.ts -s <source file>Web app is a client-side React application bundled with Vite.
