摘　　要：由于ISA总线数据传输率低、不能支持即插即用,兼容性差等,逐渐被性能突出的PCI总线所取代。文中采用PCI总线技术,设计实现某型号解析测图仪的控制接口。结果表明,在解析测图仪的绘图精度和硬件兼容性等方面有较大的提高。Because the interface of certain analytical plotter based on ISA bus has low velocity in transferring data,can not support plug-and-play mechanism,and has a bad compatibility,it can not meet the needs of accuracy and resolving power.In order to increase the performance,the interface was developed on PCI bus.And the result is good in both accuracy and compatibility.
