MipsWeaver is an all-purpose assembler and interpreter library for the MIPS assembly language.

Usage of this library requires the Rust compiler to be installed.

Executing a MIPS program:

cat mips.asm | cargo run

Building documentation:

cargo doc

Running integration and doc tests on the library:

cargo test

The MIPS reference is available on

• Volume I Introduction to the MIPS32 Architecture
• Volume II Instruction Set Manual
• Volume III Priveleged Resource Architecture

• All MIPS32 Instructions defined between Release 1 and Release 6
  • Excluding the exceptions in unimplemented features
  • Feature spreadsheet can be seen here
• Binary encoding of instructions

• Compile to ELF format file
• Interactive MIPS parser with WebAssembly (crate to be developed later)
• Disassembler

• Coprocessor 2 (behavior is left undefined by specification).
