通过探索不同粒度的数据级和任务级并行性，我们将高级加密标准(AES)密码的16种实现映射到一个细粒度的多核系统上，其中包括在线和离线密钥扩展。最小的设计仅使用6核用于离线密钥扩展，8核用于在线密钥扩展，而最大的设计分别需要107核和137核。与已发表的通用处理器上的AES密码实现相比，我们的设计单位芯片面积的吞吐量提高了3.5-15.6倍，能效提高了8.2-18.1倍。此外，该设计的吞吐量是TI DSP C6201的2.0倍，单位芯片面积的吞吐量是GeForce 8800 GTX的3.3倍，能效是GeForce 8800 GTX的2.9倍。
By exploring different granularities of data-level and task-level parallelism, we map 16 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, our design has 3.5-15.6 times higher throughput per unit of chip area and 8.2-18.1 times higher energy efficiency. Moreover, the design shows 2.0 times higher throughput than the TI DSP C6201, and 3.3 times higher throughput per unit of chip area and 2.9 times higher energy efficiency than the GeForce 8800 GTX.
