Author here, thanks for all the comments, didn't expect this to get picked up.

I've been working on speeding up RISC-V emulation for work and wrote this up as I went. Still learning this space, so I'd be keen to hear from people who've worked on emulators or binary translation, especially where you think this approach falls short

Neat, I guess this gets you the same output as a per-instruction translator without having to run an assembler and linker over the whole program. I should try this and add it to the post for completeness

Yeah, I went back and forth on the title. It's definitely not an interpreter. I still think of emulation as the umbrella term though, running code for one architecture on another, with interpretation and dynamic/static recompilation being different ways to get there

Hey, author here. That's fair, I didn't have the background. I knew interpreters would be slow, I just didn't expect it to still be ~10x after all the optimizations. After reading about it more though, that does seem to be the norm

I’ve been working on speeding up RISC-V emulation for my work, and I wrote a detailed blog about my learning. For some benchmarks, it now reaches roughly 85% of equivalent native throughput on an Apple M3.

I’d appreciate feedback from people who have worked on emulators, binary translation, JIT/AOT compilers.
