Program skipping method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a program skipping method and device. The method comprises the following steps of: obtaining a skip instruction which is preset at a first instruction addressand enters an SEC stage of the UEFI, wherein the first instruction address is electrically executed on the MIPS processor; Executing jump instructions, entering an SEC stage program of the UEFI, wherein the SEC stage program comprises an assembly program and a high-level language program; Executing an assembly program; when the MIPS processor is initialized, locking a target buffer space requiredfor executing a high-level language program; copying a high-level language program from a nonvolatile memory to the target buffer space; skipping from the assembly program to a target buffer space torun a high-level language program; According to the method, the SEC stage of the UEFI can be entered under the MIPS architecture; In the assembly program execution stage, the preparation work needed by high-level language program execution is completed, jumping from the assembly program to the high-level language program is achieved, the problem that an existing UEFI code cannot be directly applied to an MIPS framework is solved, the development cost is reduced, and the development efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a program jumping method, a program jumping device, an electronic device and a readable storage medium. Background technique [0002] UEFI (Unified Extensible Firmware Interface, Unified Extensible Firmware Interface) is a standard that describes a type interface in detail, and is used for an operating system to automatically load an operating system from a pre-started operating environment. The interface provided by UEFI to the system includes boot services (Boot Services) and runtime services (RuntimeServices). [0003] The first stage of UEFI power-on operation is the SEC (SECurity, security verification) stage. This stage mainly completes some basic configurations of the CPU so that it can start running UEFI code. This stage includes the assembly code related to the processor architecture and the general C language code that has nothing to do with the processor architectur...
