Abstract :
Coarse-grained reconfigurable architectures (CGRAs) present an appealing hardware platform by providing high computation throughput, scalability, low cost, and energy efficiency, but suffer from relatively high control path power consumption. We take the concept of a token network from dataflow machines and apply it to the control path of CGRAs to increase efficiency. As a result, instruction memory power is reduced by 74% , the overall control path power by 56%, and the total system power by 25%.
