FEATHER Tutorial

Tutorial materials for the FEATHER accelerator, presented at RAIC.

Tutorial website: https://maeri-project.github.io/feather_tutorial/FEATHER.html

Overview

This repository contains the compiler backend and hardware design materials for the FEATHER tutorial. Participants work through compiling attention kernels (XLA-HLO IR) to FEATHER's MINISA instruction set using both the ACT compiler backend and the Allo hardware design framework.
