OpenRISC JavaScript emulator emulates up to 16 cores

Online OR1K Emulator running Linux. Contribute to s-macke/jor1k development by creating an account on GitHub.

OpenRISC JavaScript emulator emulates up to 16 cores launched on November 8, 2014 with 43 votes and more than 90% of that year's launches. The site was still online in September 2026, 11 years on.

In plain words

The OpenRISC JavaScript emulator is a development tool that simulates the OR1K processor architecture running Linux directly in a web browser. It can emulate up to 16 processor cores simultaneously, allowing developers to test and run OR1K-based software without dedicated hardware. The project is open-source and hosted on GitHub, where developers can contribute to its ongoing development.

    I've been exploring new ways of testing Ghidra processor modules. In this repo, I was able to emulate NES ROMs in Ghidra to test its 6502 specification, which resulted in finding and fixing some bugs. Context: Ghidra is used for reverse engineering binary executables, complementing the usual disassembly view with function decompilation. Each supported architecture has a SLEIGH specification, which provides semantics for parsing and emulating instructions, not unlike the dispatch handlers you would find in interpreters written for console emulators. Emulator devs have long had extensive test…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
