Description

technical field [0001] The invention relates to the field of embedded reconfigurable systems, in particular to a large-scale coarse-grained embedded reconfigurable system and its processing method applied in the fields of communication and encryption. Background technique [0002] General-purpose processors and application-specific integrated circuits (ASICs) are two mainstream methods in the field of traditional computer system architecture. However, with the increasing demand for system performance, energy consumption, time-to-market and other indicators in the application field, the disadvantages of these two traditional computing models are exposed. [0003] The general-purpose processor method has a wide range of applications, but the calculation efficiency is low. Although the application-specific integrated circuit can improve the calculation speed and calculation efficiency and meet the performance requirements, the flexibility of the ASIC device is very poor.
