Abstract:
Aiming at promoting the reusability and integratability of automotive software, this paper refers to the automotive open system architecture standard AUTOSAR Operating System(OS) specification which is a standard for automotive industry, discusses the design approach of function modules such as schedule table, OS-application and timing protection on the basis of OSEK/VDX OS. It implements it on MC9S08DZ60, which is a freescale 8-bit microprocessor chip. It tests storage demand and real-time performance of the system, the result of which shows the system meets the requirements of embedded real-time OS.
Key words:
AUTOSAR specification,
OSEK/VDX specification,

摘要：
针对汽车电子软件的复用和集成问题，参照汽车开放系统架构标准AUTOSAR操作系统规范，在OSEK/VDX操作系统的基础上增加调度表、OS-应用和时序保护等功能模块，并以MC9S08DZ60芯片为硬件平台实现一个符合该规范的操作系统内核，对其存储要求和时间性能进行测试。测试结果表明，该操作系统能满足嵌入式系统的存储要求和实时要求。
