MCHPRS VS chungus-2-assembler

You can compile redstone using Rust though, see https://github.com/MCHPR/MCHPRS and https://youtu.be/-BP7DhHTU-I

Someone made a Redstone JIT compiler.

I don't know if you know about MCHPRS. It's a multi-threaded self-hosted MC Server made specifically for redstone. It gives you more control over redstone.

It sure is! https://github.com/MCHPR/MCHPRS

The relevant bit is https://github.com/MCHPR/MCHPRS and Rust snippet starting from 0:25

Pretty cool.

The program itself was written in an existing intermediate language called URCL, which was then compiled to CHUNGUS2 assembly. CHUNGUS2 is the processor made with Minecraft's redstone mechanics. The processor was emulated for development, but the demo is running on MCHPRS, a Minecraft server that uses Wasmtime's Cranelift to JIT the redstone operations, which are represented as a weighted directed graph. Before MCHPRS optimizing redstone performance using compiler techniques was not thought to be possible. With MCHPRS the demo takes 9 hours to run, it would take decades without it.

Yes, the 2,000,000x slowdown mentioned in the trailer is relative to vanilla. But because it would take a decade to record this footage at that speed, they're using this Minecraft server implementation optimized for redstone: https://github.com/MCHPR/MCHPRS

It looks like these are the only existing items, which were enough to accomplish the goals of this project

how can this processor run games like Tetris https://github.com/sammyuri/chungus-2-assembler/blob/main/saves/tetris.txt (compiled size 11kb), if it supports only 4kb attachable program memory?
