Goal: Split Compiler LLVM LLVM – DRESC bytecode staticdeployment time optimized architecture description compiler strategy ML annotations C code ADRES executable

ADRES Two functional views/operation modes Features heterogeneous FUs, local RFs, direct connections between FUs Reconfigurable every cycle Tightly coupled to control processor IMEC ADRES CGRA Coarse-Grained Reconfigurable Array

What does the DRESC scheduler do?

Scheduling Phases 1.Determining the clusters 2.Recurrence Cluster Scheduling 3.Non-recurrence Cluster Scheduling

1. Determining the clusters

2. Recurrence Cluster Scheduling I.Schedule incoming tree of cluster II.Schedule recurrence cluster

2.I Schedule incoming tree of cluster

2.II Schedule recurrence cluster All recurrence clusters are scheduled in a reverse manner
