Abstract

The invention belongs to the technical field of airborne embedded software, and particularly relates to a lossless compression guide processing method for an executable file under a partition operating system, aiming at an executable file which is an executable file subjected to engineering verification based on a domestic operating system ACoreOS653. The method comprises the following steps: firstly, preprocessing the executable file, and completing lossless compression guide processing of the executable file through lossless compression storage, compression-decompression correctness verification after power-on and decompression operation. According to the method, normal operation functions of the platform are ensured, meanwhile, a large amount of software storage space can be released, the problem that executable files are increasingly increased when the storage space of the platform is insufficient is solved, and support is provided for system reconfiguration.

Description

technical field [0001] The invention belongs to the technical field of airborne embedded software, and in particular relates to a lossless compression booting processing method for executable files under a partitioned operating system. Background technique [0002] Tianmai 2 is the only multi-application and multi-task-oriented partition real-time operating system in China with completely independent intellectual property rights, which meets the application requirements of integrated and modular avionics systems, and has been widely used in the aviation field . At the same time, as an important part of the avionics system, airborne embedded software is required to have high reliability and high security. In order to ensure the execution speed of embedded software and system reliability, airborne embedded software is generally solidified in the memory chip or the internal memory of the processor, rather than in an external carrier such as a disk. However, the internal memor...
