Abstract: The present disclosure discloses an information security application-oriented reconfigurable system chip compiler and an automatic compilation method. The method includes the following steps: firstly, inputting a source program of a cryptographic algorithm; then, executing a software compilation function syntax check of the source program, and when the check result is passed, performing compilation mapping using a compiler; next, executing the cryptographic algorithm by simulation running using a simulator, and generating a configuration code by a simulator array; and finally, guiding a hardware behavior operation using a binary configuration code file generated by the simulator. The reconfigurable system chip compiler includes a source program input module, a software compilation function verification module, a compilation mapping module, a simulation execution module, a configuration code generation module, and a hardware debugging module.

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.
