In order to improve the performance of block cipher, clustered processor structure is put forward. How schedule data in multiple clusters will influence directly. Based on analyzing characteristics cipher flow, we propose a scheduling scheme according width and operation mode. The final algorithm mapping experiment results show that not only meets distribution demand different algorithms, but also reduces number instructions algorithms need, thus it can enhance throughput most algorithms.
