By exploring different granularities of data-level and task-level parallelism, the authors map 4 implementations of an Advanced Encryption Standard (AES) cipher with both online and offline key expansion on a fine-grained many-core system. The smallest design utilizes only six cores for offline key expansion and eight cores for online key expansion, while the largest requires 107 and 137 cores, respectively. In comparison with published AES cipher implementations on general purpose processors, their design has 3.5-15.6 times higher throughput per unit of chip area and 8.2-18.1 times higher energy efficiency.
