多窗口剪切域代价分析及优化算法

Researches into the costs of clip region for multiwindow system and an optimal algorithm

简要的分析了现代的多窗口系统中使用的一项关键技术——剪切域的时间和空间消耗代价,根据多窗口操作和嵌入式系统的特点提出了一种适合在嵌入式图形中间件中应用的优化的剪切域切换算法,应用及模拟实验表明,该算法可行并且高效。

To improve the performance of embedded graphic midware, this paper analyzed the time and space complexity of clip region which is a key technique used in the multiwindow system, and proposed an optimal switching algorithm according to the characteristics of multiwindow operation and embedded system. Application and simulation test have proved that the algorithm works well and runs faster.
