基于相异编译器的安全计算机平台交叉编译环境设计

Design of Diversity-compiler-based Cross-compiling Environment for Secure Computer Platform

由于轨道交通信号系统具有安全苛责性要求,因此信号设备安全计算机平台双通道通常采用相异算法.介绍了几种编译环境的优缺点,通过构建基于CodeWarrior及GCC编译器的双通道交叉编译环境,实现了一个可适配不同上层应用软件的通用Makefile模板,达到简化开发环境、提高研发效率的目的.

Due to the safety-critical requirements of the signal system for rail transit,the dualchannels of secure computer platform of signal equipment usually adopts diversity algorithm.The advantages and disadvantages of vseveral compilation environments are introduced.By constructing a dual-channel cross-compiling environment based on CodeWarrior and GCC compilers,a common Makefile template that can be adapted to different upper applications is implemented to sim plify the development environment and to improve the efficiency of research and development.
