Description

technical field [0001] The invention relates to the field of embedded reconfigurable systems, in particular to a large-scale coarse-grained reconfigurable computing system and a processing method thereof applied in the field of information security. Background technique [0002] General Purpose Processor (GPP) and Application Specific Integrated Circuit (ASIC) are the two mainstream methods for implementing encryption and decryption algorithms in the information field. However, although the ASIC implementation can achieve extremely high performance, area and energy efficiency by optimizing the data path and pipeline for a specific cryptographic algorithm, this implementation has poor flexibility and is difficult to meet the reconfigurable requirements of the cryptographic algorithm, which is not ideal. implementation plan. GPP is implemented in a command-driven manner, and its data path adopts a general architecture, which can adapt to various types of applications and has ...
