A Edge-Centered High Energy-Efficient Mapping Algorithm for Cipher Logic Array

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.
