智能高分辨率彩色图形系统NHGCB的软件

The Programming of the Intelligent High-Resolution Color Graphics System NHGCB

本文介绍了自行设计研制的NHGCB高分辨率彩色图形系统。该系统以INTEL82720为核心,并自含MCS-51单片机子系统,既可独立进行图形显示,又可与IBM等微机相连构成多处理机图形处理系统。NHGCB支持最高分辨率为1024×1024,可同时显示16/4096种麒色。本文重点介绍该系统的软件结构及绘图程序设计方法,包括NHGCB的工作方式、主机与单片机子系统的通讯与控制程序,以及GDC的编程方法等。

This paper describes the NHGCB,a high performamce intelligent color graphics system,which is based on an INTEL 82720 GDC,and has a built-in MCS-51 microcontroller subsystem. It can be used as an independent graphics system or, together with IBM or other microcomputer system as a multiprocessor graphics processing system. The NHGCB can display up to 1,024 by 1,024 pixels with 16 of 4,096 colors. This paper mainly describes the programming of the NHGCB graphics controller system, which involves the operation mode,the communication between the Hosier and the MCS-51 microcontroller subsystem and the GDC programming.
