摘要
本文论述一种自行设计与实现的彩色图形系统NHGCB。这是一种具有多处理机智能环境采用视频存贮器分体技术的高性能图形控制系统。它以INTEL 82720 GDC为核心,并自含单片机子系统,既可以独立成为一个智能图形系统显示各种彩色图形;又可与微机一起构成一个多处理机图形处理系统。NHGCB支持最大1024×1024分辨率,可同时显示16/4096种颜色。
This paper describes a high performance intelligent color graphics system NHGCB, which uses the design of partitioning the video memory into several different banks and provides a multiprocessor environment. The NHGCB is based on an Intel 82720 GDC, and provided with a built-in MCS-51 microcontroller subsystem. It can be used as an independent graphics system or, together with an IBM or other microcomputer systems, as a multiprocessor graphics processing system. The NHGCB can display up to 1024 ×1024 pixels with 1b /4,096 colors.
