【摘要】 针对Ethernet/IP通信处理器的开发,采用S3C2410ARM9微处理器和Windows CE.NET嵌入式操作系统,建立了通信处理器的BootLoader和I/O接口驱动程序。BootLoader与硬件高度相关,担负着初始化系统硬件和引导操作系统的双重任务。而I/O接口驱动程序使操作系统自动识别外围数据采集设备,为应用程序对底层设备的操控提供服务。实验测试表明该Ethernet/IP通信处理器运行稳定、可靠。更多还原

【Abstract】 Aiming at the design of the Ethernet/IP communication processor, this paper adopts S3C2410 ARM9 microprocessor and Windows CE.NET operating system to develop the communication processor’s Boot Loader program and I/O interface’s driver. The Boot Loader program, which is highly relevant to the hardware, initializes hardware platform and boots Windows CE.NET OS. While the I/O interface’s driver makes the OS detect peripherals automatically, and provides services for the applications to control the bottom equipments. Experimental results show that the Ethernet/IP communication processor operates steadily and credibly.更多还原
