基于图层的嵌入式终端界面

Embedded Terminal Interface Solution Based on Graphics Plane

嵌入式终端的发展,对图形界面提出了友好、低廉的要求。通过分析对比几种图形处理机制的特点,考察了软件多图层机制的可行性;根据软件多图层机制的原理及结构,提出了软件整合多个图层的设计方案,并实现了多图层的图形界面;并在单图层机制及软件多图层机制上,对实现的界面风格及内存耗费的优劣差异进行了测试。

With the development of embedded terminals, an increasing number of users demand friendlier user interface and lower cost graphics system. After analyzing the characteristics of different graphics processing mechanisms, the study on software-based multiple graphics-planes mechanism shows the feasibility of meeting user demand. According to the principles and the architecture of this mechanism, a way of how to blend multiple planes using software is brought forward, and a nice user interface is successfully implemented. The test of the interface style and the memory consumption state show the capability difference between single-plane mechanism and software-based multiple-plane mechanism.
