基于ARM系统高分辨率彩屏设计方法

An Approach to High Resolution Color Display in ARM System

随着嵌入式系统的使用越来越广泛,它可能需要使用较大的LCD屏或CRT作为显示终端,而目前常见的处理器的显示性能无论在图形显示速度还是分辨率上都达不到要求。本文以ARM体系结构为中央处理器,结合SiliconMotion公司的SM501为2D图形加速芯片,提出了在嵌入式系统中1280×1024高分辨率和24位真彩显示的设计方法。

Large-size LCD or CRT may required as the display device of an embedded system. However, the display performance of an embedded system using one of the existing processors alone cannot meet the requirement of complicated images displaying neither in resolution nor in speed aspect. Based on 2D graphics acceleration chip SMS01, an approach to high resolution （1280×1024） and 24bit-color display in ARM system is given.
