摘　　要：EPICS是由美国阿贡国家实验室(ANL)和洛斯阿拉莫斯国家实验室(LANL)联合开发的控制系统软件包。PCI是一种局部总线,用于连接计算机中的硬件设备。VME是一种异步总线,稳定可靠,在EPICS控制系统中应用广泛。开发EPICS的VME总线驱动程序,需要对计算机的地址映射等机制有充分的了解,因此需要对这些内容进行研究。论文描述了在实时操作系统VxWorks下访问VME设备的原理和方法,以及EPICS对VME设备的支持。EPICS（Experimental Physics and Industrial Control System） is a set of software tools,libraries,and applications developed collaboratively by Argonne National Laboratory and Los Alamos National Laboratory of America.PCI is a local bus for attaching hardware devices in a computer.VME is a synchronous bus,stable and reliable.It is widely used in EPICS control systems.Developing EPICS drivers for VME bus needs the knowledge of computer mechanisms such as memory mapping.So we need to study such contents.It describes theprinciple and method on how to access VME devices on the real-time operating system VxWorks and the EP-ICS support for VME.
