| Abstract | Modulo counter based control of coarse-grained reconfigurable arrays (CGRAs) makes them inefficient for applications with multiple execution modes. This work presents an enhanced architecture and accompanying tool chain that add branching control flow to CGRAs. Offset pipelined scheduling leads to a challenging routing problem. The EveryTime router presented here is an architecture adaptive approach that allows paths to consume resources across modes when necessary and share resources when possible to mitigate the added complexity. The Offset Pipelining tool chain provides 2.1 times better average performance on the same device size with approximately the same channel width compared to a modulo scheduling based tool chain and architecture.
