Overview

mighf is a minimal, educational micro-architecture and emulator project.
It lets you experiment with a simple CPU, custom instruction set, and assembly-like programming—all in software.

Features

• Simple 8-register, 1KB memory micro-architecture
• Assembler and Runtime made in pure C
• In-terminal drawing with ASCII graphics
• Interactive shell for loading and running programs
• Easily extensible instruction set

Getting Started

Build

gcc source/mighf-unix-msys.c -o mighf.bin

Note

The mingw-w64 toolkit can also be used to compile mighf It was tested by me.

Run

./mighf.bin

Example

Load and run an assembly program:

coreshell> load rom/rom.s
coreshell> run

Assembly Example

TDRAW_CLEAR
MOV R1, 10
MOV R2, 5
TDRAW_PIXEL R1, R2, '*'

Tip

To learn about the mighf assembly language read the Docs
