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

2. 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

3. What does the DRESC scheduler do?

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