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.
