ppc750cl

Rust tools for working with the PowerPC 750CL family of processors.

Rust crates

rustup components add rustfmt
cargo run --package ppc750cl-genisa
cargo build --release

Python module

python -m venv env
source ./env/bin/activate
pip install maturin
maturin build -m ./disasm-py/Cargo.toml

Instruction Set

For those unfamiliar with PowerPC, here are some basics.

  • PowerPC 7xx is a family of RISC CPUs produced from 1997 to 2012.
    • They operate with 32-bit words and every instruction is 32-bits wide.
  • This project focuses (only) on compatibility with the PowerPC 750CL.
    • This chip is famously packaged as codename "Broadway" for the Nintendo Wii.
    • Its predecessor PowerPC 750CXe is used in the Nintendo GameCube.
    • It adds a "paired-singles" SIMD unit and a bunch of other instructions.

isa.yaml

The file isa.yaml contains a full definition of the PowerPC 750CL instruction set.

It powers the disassembler, assembler, and Rust/Python bindings code analysis tools.

Similarly to LLVM TableGen, the program ppc750cl-genisa generates a Rust file implementing an instruction decoder.
