静电绘图仪接口板设计

The Interface Board Design of the Electrostatic Plotter

文章叙述了该接口板的硬件设计及工作原理。由于采用了8089IOP器件作为接口板的核心部件,并接成远程工作方式,使传送数据和执行程序都集于它一身,使它与主机CPU能并行工作,减轻了主机的工作负担。

This paper discusses the hardware design and working principle of the interface board. As the 8089 Iop is used as the main working element in this interface board and making it works at remote working mode. This not only make data transfer and programme execution on the same CPU, and makes it working together with the host computer parallized, but also reduce the burden of the host computer.
