摘要
提出一种以AT91SAM9263处理器为核心芯片、采用嵌入式Linux2.6内核和MiniGUI3.0图形系统的数字加密电话系统GUI的设计与实现方案。采用双缓冲技术与多张图片交替显示的方式解决了MiniGUI的动画抖动问题和屏幕刷新负载过大导致的屏幕抖动问题。
A scheme of digital encryption telephone system is proposed. AT91SAM9263 processor and embedded Linux2. 6 kernel are adopted as core chip and operating system respectively. In addition, MiniGUI3.0 graphics system is adopted to develop the graphics interface of the system. Two problems, i.e. animation shaking of MiniGUI and screen shaking caused by screen refresh overload are solved by using bi-buffer technology and the method of showing multiple pictures alternately.
