嵌入式图形系统μC/GUI的动态内存分配的研究

Research on Dynamic Memory Distribution of Embedded μC/GUI

在进行嵌入式系统的开发的过程中,都必须设计出易于操作的人机互动操作界面。完成此工作会占用开发者过多的时间,甚至以失败告终。文中为开发者论述了一款新系统,即嵌入式图形系统μC/GUI。它不仅具有很好的移植性,而且还具有灵活、简洁、高效、可方便剪裁、程序占用空间小等优点,因此在嵌入式系统行业中得到了广泛的应用。为了提高μC/GUI的实时性,在研究了此系统的运行机制之后,设计了一个动态内存分配的方案。此方案在实验中取得了良好的结果,是非常有效的。

When developing the embedded system,it is necessary to research the operation interface. But finished the work will take most time, even failed at last. So introduces the system called embedded graph system μC/GUI. It is transplantable, flexible, simple and efficient, which can be dipped easily and applied widely. To improve the real-time performanee of μC/GUI, researches into the operating prineipium of this system, then designs a scheme for dynamic memory distribution, which proves to be very praetieal and efficient in the experiments.
