Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.
It features a relatively simple instruction set but can be used to write moderately complex assembly programs, and is a viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages.
This project is a Little Computer 3 virtual machine written in Rust programming language. It follows the online guide from Write your Own Machine by Justin Meiners and Ryan Pendleton. The virtual machine components are organized as below:
| Filename | Description |
|---|---|
| main.rs | Program entry point for image loader and simple CLI implementation |
| cpu.rs | Implementation of a virtual CPU or virtual machine |
| instruction.rs | Declaration of the enumeration of instructions |
| trap.rs | Declaration of the enumeration of trap routine |
| register.rs | Registers and conditional flags |
| constant.rs | Constants |
