针对现有可重构分组密码系统资源利用率低的问题，在分析分组密码算法处理特征的基础上，提出基于Crossbar互连的可重构分簇式分组密码处理架构RCCPA（Reconfigurable Clustered Cipher Processing Architecture），研究了RCCPA的互连网络、分簇式寄存器堆及配置方式。RCCPA通过重构互连网络可将各处理簇动态地重构成4个32 bit簇、2个64 bit簇和1个128 bit簇，并可将可重构处理单元RCU（Reconfigurable Cipher Processing Unit）组织成多级流水的处理路径，满足了分组密码处理灵活性的要求，提高了RCU的利用率。采用RCCPA实现AES/DES/IDEA的处理性能分别达到了2867．2 Mbps、1442．6 Mbps、1462．4 Mbps。

In light of the problem that existing reconfigurable block cipher system has low efficiency in resource utilisation,on the basis of analysing the processing characteristics of block cipher algorithm,we propose a reconfigurable clustered block cipher processing architecture (RCCPA)which is bases on Crossbar mutual-connection,study the mutual-connection network of RCCPA,the clustered registers file and its configuration mode.The RCCPA can dynamically reconfigure each processing cluster into four 32-bit clusters,two 64-bit clusters and one 128-bit cluster through the reconfiguration mutual-connection network.Besides,it can organise the reconfigurable processing RCU into a multi-pipeline processing path,which satisfies the flexibility demand of block cipher processing and improves the utilisation rate of RCU.The performance of implementing AES/DES/IEDA using RCCPA can reach as high as 2 867.2 Mbps,1 442.6 Mbps and 1 462.4 Mbps.
