Efficient AES cipher on coarse-grained reconfigurable architecture

Abstract

By exploring the mapping schemes with dataflow graph (DFG) transformation and different granularity of task-level parallelism, we presented various AES implementations on a coarse grained reconfigurable architecture (CGRA) to meet the requirements raging from high performance to low power. In comparison with published AES cipher implementations on programable processors, our AES cipher has 14.7∼121.4× higher energy efficiency. Moreover, the design shows the advantage over other CGRAs with 1.3∼4.5× energy efficiency improvement.
