基于MPC860嵌入式处理器和Vx Works的文件与实时图像传输

Files and real-time videos transmission based on MPC860 embedded microprocessor and VxWorks

利用WindRiver公司的实时操作系统 (RTOS)VxWorks提供的丰富而标准的sockets编程接口 ,多任务机制 ,高效的实时任务的产生、调度、资源分配机制以及对外界输入产生最快响应的能力 ,运用嵌入式软件开发系统TornadoⅡ ,介绍了基于研制的MPC860嵌入式处理器进行软件开发的过程 ,在底层使用以太网作为传输媒介 ,在传输媒介的上一层 ,使用TCP/IP和UDP/IP协议 ,完成局域网间IP数据的转发 ,实现了嵌入式系统控制的文件。

This paper presents a software scheme for communication controllers based on MPC860 embedded microprocessors VxWorks RTOS and TornadoⅡ, which targets transmitting files and real time videos using Ethernet as transmitting medium and transferring TCP/IP packet in LAN (local area network). Considerations of utilizing the VxWorks's socket program, multitask mechanism, efficient real time tasks management and quick reaction capability are also introduced.
