摘要
AUTOSAR(汽车开放式系统架构)平台可分为3层:应用层、运行时环境和基础软件,其中基础软件又包括系统服务、ECU抽象层和uC抽象层。所有驱动程序都包含在uC抽象层和ECU抽象层中。存储器驱动提供了对不同存储设备的访问接口。根据AUTOSAR规范,在MPC5633M微控制器上,设计并实现了Flash驱动程序。提出的设计与实现的方法同样适用于其他设备驱动的开发。
The AUTOSAR platform consists of three layers:the application layer, the runtime environment, and the basic software which includes system services, EAL(ECU abstraction layer) and uCAL(uC abstraction layer).Device drivers belong to uCAL and EAL.The memory device driver provides access to different memory devices.In the paper, the specific design of AUTOSAR is followed and a Flash driver on MPC5633M microcontroller is implemented.The proposed procedure is applicable to other device drivers.
