基于DSP运动控制器的PCI总线设计

运动控制器设计是基于计算机标准PCI总线的,它是把具有开放体系结构,独立于计算机的运动控制器与计算机相结合构成。采用运算能力强的DSP芯片作为CPU,32位的PCI总线为硬件接口。设计了以PCI9052为接口芯片的PCI总线接口方案,详细描述了PCI9052的配置方法,并为PCI总线开发了驱动程序和上位机通讯应用程序,实现了从上位机到DSP运动控制器的高速数据传输。

The motion controller in this paper is based on standard computer PCI bus;it combined an open-system structure and computer-independent motion controller with computer.It used high-performance DSP for CPU,and PCl bus for interface.This paper made a design of standard PCl interface for DSP based motion controller,elaborated on configuration of PC19052,and developed the driver program and application program for the hardware,realized the high speed data transfer between DSP and host PC.
