raki

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.

use raki::Isa;
use raki::decode::Decode;
use raki::instruction::Instruction;

let inst: u32 = 0b1110_1110_1100_0010_1000_0010_1001_0011;
let inst: Instruction = match inst.decode(Isa::Rv32) {
    Ok(inst) => inst,
    Err(e) => panic!("decoding failed due to {e:?}"),
};
println!("{inst}");
// --output--
// addi t0, t0, -276
