基于FIFO帧存储的任意视频图象信号发生器

Arbitrary video signal generator based on FIFO frame memories

提出一种基于先入先出 (FIFO)帧存储的任意视频图象信号发生器的设计方法 ,介绍了系统的软件和硬件构成 ,特别是帧存储器的设计、软硬件接口方法以及视频图象信号的生成过程 ,并介绍在电视墙调试中的应用实例 .

A method for designing arbitrary video signal generator based on FIFO frame memories is presented. This paper introduces the system architecture including software and hardware, emphasizing on the design of the frame memories, the interface method of the software and hardware, and the generation of video signals. Finally the examples of testing signal for video wall system are shown.
