| 摘 要： | 介绍了一种基于共享帧存结构的双通道视频控制器设计。系统以单处理器、单视频控制器同时驱动两路画面不同的彩色显示器，完成复杂画面的实时生成。视频控制器采用分时控制原理，对存储于同一物理帧存储器的双路图形信息，可准确地生成地址刷新时序和视频控制时序，并行输出两路同步的视频流。该设计用于“一驱二”图形发生器，已成功应用于某型直升机玻璃座舱显示系统。

| Abstract: | As key component of embedded graphics generator, one video controller can accomplish twin channels video control mission when using time sharing technology. This kind of video controller can accurately generate video control time sequence of two frame graphics data in the same time. And the two frame graphics data are storaged in one physical frame memory. This kind of video controller has been used in the glass cockpit display system of a helicopter. |
