1 概述内嵌式VXI总线控制计算机是用来控制VXI系统的高性能平台。它占用1—4个C尺寸插槽的位置空间。这种内嵌式VXI总线控制计算机以486处理器和PC AT结构为基础,并具有坚实的硬盘和3.5英寸的软驱控制器,在一块芯片上用高性能的常规门阵列实现VXI的多种功能。在前面板上设有端口连接到外部的硬盘驱动器、软盘驱动器、VGA显示器、GPIB接口、串并口、VXI时钟触发信号等。在VXI软件的控制下,就可以直接控制VXI的寄存器、存储器和触发器,从而实现VXI总线的管理功能。
1 Overview The embedded VXI bus control computer is a high-performance platform used to control VXI systems. It occupies space for 1-4 C-size slots. This embedded VXI bus control computer is based on a 486 processor and PC AT architecture with a solid hard drive and a 3.5-inch floppy drive controller for multiple VXI functions on a single chip with a high performance conventional gate array . The front panel has ports for connecting to external hard disk drives, floppy disk drives, VGA displays, GPIB interfaces, serial and parallel ports, VXI clock triggering signals, and more. Under VXI software control, you can directly control the VXI registers, memory and flip-flops in order to achieve the VXI bus management functions.
