## What it is
MIAOW is an open source GPU implementation of the AMD Southern Islands ISA written in Verilog. It was developed as a research project at the University of Wisconsin-Madison under Professor Karu Sankaralingam.

## Use cases
- implement an open source GPU from scratch
- study GPU microarchitecture in hardware description language
- simulate or synthesize an AMD Southern Islands compatible GPU
- research GPU compute unit design
- learn GPU ISA implementation in Verilog

## When to choose
- you need an open hardware GPU design based on a real ISA
- you are doing academic research on GPU microarchitecture
- you want a Verilog GPU implementation to modify or extend

## When to avoid
- you need a production-ready GPU with driver support
- you need a GPU simulator rather than RTL hardware implementation
- you need modern GPU ISA support beyond Southern Islands

## Facets
- artifact type: library
- maturity: maintenance
- function: gpu-computing, simulation, graphics
- domain: hardware, gpu-computing, computer-vision
- platform: cpp
- tags: gpu, verilog, amd-southern-islands, isa-implementation, open-source-hardware, research
