Title:

Mapping control flows onto CGRA

Abstract:

Coarse-grained reconfigurable architecture typically has an array of processing elements controlled by a centralized unit. This makes it difficult to execute programs having control divergence among PEs without predication. However, conventional predication techniques have a negative impact on both performance and power consumption due to longer instruction words and unnecessary instruction-fetching/decoding/nullifying steps. This talk presents fast and power-efficient predication mechanisms.
