摘要
OSEK规范是一个汽车电子开放式系统及其接口的软件规范,MPC555是Motorola公司开发的高性能车用微控制器。结合这两者的技术特点,提出了在MPC555硬件平台上实现符合OSEK规范的车用嵌入式实时操作系统的设计思想,介绍了操作系统实现的集成交叉开发环境,详细分析了该操作系统的组成与实现,并对其实时性和存储要求进行了评估。
OSEK/VDX is an industry standard for an open-ended architeture for distributed control units in vehicles.The idea
of designing an embedded real-time operation system(RTOS)compatible with OSEK/VDX,which has been successfully run
on MPC555,a powerful 32-bit microcontroller from Motorola was discussed.The integrated development environment(IDE)
with across-compiler used for the RTOS development was introduced.The composition and implementation of the RTOS was pre-
sented in details.Additionally,an evaluation of the real-time performance and the memory required of the OS was given.
