Abstract

The invention provides an operation environment construction method and device. The method comprises the following steps of: firstly locking a cache and taking the locked cache as an analog memory; obtaining a corresponding virtual address according to a physical address of the analog memory; setting a heap pointer and a tack pointer in the analog memory according to the virtual address; and setting each section for heap pointer addressing in the analog memory according to an executable and linkable-format ELF file structure. According to the method and device, a C language operation environment is constructed, and the developers can compile memory configurations by directly using a C language without using an assembly language, so that the development and test of the developers are convenient.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for constructing an operating environment. Background technique [0002] PMON is an open source software that combines basic input output system (BIOS) and bootloader functions. It is mostly used in embedded systems. The system based on the microprocessor without interlocked piped stages (MIPS) architecture uses PMON as the BIOS-like and bootloader, and has done a lot of perfect work on the basis of it, supporting BIOS startup configuration, kernel loading, Program debugging, memory register display, setting and memory disassembly, etc. [0003] At present, part of the PMON source code is written in assembly language, such as the memory configuration part of the BIOS startup configuration in the PMON source code. When developing and testing, developers need to use assembly language to read or rewrite code parts such as memory configuration. [0004] Howeve...
