The author implements a full LC-3 instruction disassembler in Haskell, demonstrating how functional programming's pattern matching and algebraic data types make it natural to model the 16-bit instruction format and its encoding rules. The piece highlights the expressive power of Haskell for parsing tasks and provides a working reference implementation for educational purposes.
Background
LC-3 is a classic educational assembly language used in computer science courses (notably MIT's 6.004) to teach computer organization. A disassembler that translates LC-3 machine code back to human-readable assembly is a standard tool for understanding low-level programming.
