摘要
摘要:为解决密码算法在粗粒度可重构密码逻辑阵列(CRCLA)上映射性能不高及编译时间长的问题，该文提出一种密码算法和硬件资源的描述形式，在映射过程中能够更加直观地显示各个资源的占用情况；并通过分析密码算法运算特征与粗粒度可重构密码逻辑阵列硬件结构的内在关联，以减少关键路径延时为目标，提出了一种以边为中心的密码逻辑阵列高能效映射算法(ECLMap)。通过边映射来指导节点映射，结合相关映射策略，引入回溯机制来提高映射成功率。在仿真平台下对多种密码算法进行实验，相比于其他通用的映射算法，结果表明该文提出的算法映射性能最佳，在算法能效上平均提升了约20%，同时在编译时间上平均提升了约25%。实现了算法的高能效映射。

Abstract:In order to solve the problem of low mapping performance and long compilation time of cipher algorithms on Coarse-grained Reconfigurable Cipher Logic Arrays (CRCLA), a description of cryptographic algorithms and hardware resources is proposed, which can display the occupancy of each resource more intuitively during the mapping process. Then by analyzing the inherent relationship between the cryptographic algorithm operation characteristics and the coarse-grained reconfigurable cipher logic array hardware structure, with the goal of reducing the critical path delay, an Edge - centric Cipher Logical array Mapping (ECLMap) algorithm is proposed. Using edge mappings to guide the mapping of nodes, combined with relevant mapping strategy, the backtracking mechanism is introduced to improve the success rate of mapping. Compared with other common mapping algorithms, the results show that the algorithm proposed in this paper has the best mapping performance, with an average increase of about 20% in the algorithm energy efficiency and about 25% in the compilation time. The high-efficiency mapping of the algorithm is realized.
