摘要
ADV7180是嵌入式视频监控终端的采集模块常用的视频解码芯片,本文首先分析ADV7180的硬件连接接口,然后具体阐述如何在嵌入式Linux操作系统中实现ADV7180的驱动程序,包括系统的初始化、中断的设计与处理、DMA的处理等。
ADV7180 is a widely used video decoder in the embedded video supervisory terminal. In this paper, we first analyze the hardware connection interfaces of ADV7180. Then we detailedly introduce how to implement the ADV7180 device driver based on the embedded Linux, including system initialization, interrupt and DMA implementation, etc.
