Loop array mapping method of shared balance operator based on reconfigurable cryptographic algorithm

Abstract

A loop array mapping method of a shared balance operator is based on a reconfigurable cryptographic algorithm. The mapping graph is optimized by adopting a balance node operator mode, so that the mapping graph has a smallest iteration interval and a largest pipeline performance, thus solving a problem of poor pipeline performance of manual configuration and saving a great deal of human and mental labor, without adding the balance operator node manually by manual computing. In the present disclosure, a shared balance node operator solution is adopted to process a balance node of the multi-fan-out operator, so that computation resources are minimized and performance is maximized. The storage data unit SREG is used for data transfer and communication, which solves a problem that communication of data between loop bodies occupies more transfer operator resources, saves a lot of hardware resources and further improves pipeline performance.
