A program jumping method, device, electronic device and storage medium

Abstract

The embodiment of the present invention provides a program jump method and device, the method comprising: obtaining the jump instruction that enters the UEFI SEC stage preset at the address of the first instruction executed when the MIPS processor is powered on, and executing the jump instruction , enter the SEC phase program of UEFI, the SEC phase program includes an assembler and a high-level language program, execute the assembler, when the MIPS processor is initialized, lock the target buffer space required for executing the high-level language program, and convert the high-level language program from non- Copying the volatile memory to the target buffer space, jumping from the assembler to the target buffer space to run the high-level language program, can realize the SEC stage of entering UEFI under the MIPS architecture, and complete the execution of the high-level language program in the assembler execution stage The required preparatory work realizes the jump from assembler to high-level language program, avoids the problem that the existing UEFI code cannot be directly applied to the MIPS architecture, reduces the development cost, and improves the development efficiency.

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...
