Abstract

Abstract: Based on some thorough analysis of OSEK/VDX specification, this paper presents how to design an 8 bit OSEK/VDX-based Real- time Operating System(RTOS)——FDOSEK from the task schedule, resource management and event mechanism, and then realizes its kernel on the MC9S08DZ60 chip of Freescale. It tests the task schedule time and storage requirements. Test results show that FDOSEK is suitable for automotive electronics industry with a strong real-time capability and low storage requirements.

Key words: Real-time Operating System(RTOS), OSEK/VDX specification, automotive electronics, task schedule, resource management, event mechanism

摘要： 在分析OSEK/VDX规范的基础上，从任务调度、事件机制和资源管理等方面出发，研究8位嵌入式实时操作系统FDOSEK的设计，并在Freescale的MC9S08DZ60芯片上实现其内核。对FDOSEK的任务切换时间和存储需求进行测试，结果表明，FDOSEK具有较强的实时性和较低的存储需求，适用于汽车电子领域。
