# raki [](https://github.com/Alignof/raki/actions/workflows/rust.yml) RISC-V instruction decoder written in Rust. - Both 32/64bit support. - Support `rv32/64imac`, `Zicsr`, `Zifencei` extensions. - Implement Display trait for formatting. ## Usage Call the `decode` as u16/u32 method. ```rust use raki::{BaseIOpcode, Decode, Instruction, Isa, OpcodeKind}; fn main() { let inst_bytes: u32 = 0b1110_1110_1100_0010_1000_0010_1001_0011; let inst: Instruction = match inst_bytes.decode(Isa::Rv32) { Ok(inst) => inst, Err(e) => panic!("decoding failed due to {e:?}"), }; assert_eq!(inst.opc, OpcodeKind::BaseI(BaseIOpcode::ADDI)); println!("{inst}"); } // --output-- // addi t0, t0, -276 ``` ## Support - [x] BaseI (RV32I, RV64I) - [x] M - [x] A - [ ] D - [ ] Q - [x] C - [ ] B - [ ] P - [ ] V - [ ] H - [x] Zicsr - [x] Zifencei - [x] Zicntr - [x] Zicfiss - [ ] Priv (Now only supports `mret`, `sret`, `wfi`, `sfence.vma`) ## License This crate is licensed under MIT.
