摘要

为了实现某些武器系统的仿真，需要使用基于ARM9的S3C2440处理器快速移动背景图像。然而，由于嵌入式系统硬件资源的限制，通过传统的解决方案很难实现高速图像处理。本文对影响显示速度的因素进行了讨论，提出了根据DMA技术和软件算法直接写入显示缓冲区的解决方案。从而实现了快速运动图像的平滑和稳定。为嵌入式系统的图形开发提供了良好的参考。

Research of image display acceleration in embedded system

In order to achieve simulation of some weapons system, a background picture should be moved quickly by S3C2440 processor which is based on ARM9. However, it is very difficult to realize high-speed image processing through conventional solutions because of the limitations of hardware resources in the embedded system. In this paper, we discuss the factors that may affect display speed, and propose solution that is writing the display buffer directly according to DMA technology and software algorithm. As result, a smooth and stable of fast-moving images are achieved. It provides a good reference to graphics development on embedded systems.
