(1)vip 简介
这里vip 就是video in port 的缩写,"VIP0 PortA", "VIP0 PortB", "VIP1 PortA", "VIP1 PortB",总共4个口
输入数据格式有yuv422i 和yuv420t 不小的这个i和t有啥区别 yuv420t/yuv420i,
输入数据位宽有" 8-bit", "16-bit", "24-bit"
输入数据模式有
"Non-mux Embedded Sync", "Line-mux Embedded Sync",
"Pixel-mux Embedded Sync", "Non-mux Discrete Sync"
example camerlink_drv.c:
char *gCameraLink_portName[] = {
"VIP0 PortA", "VIP0 PortB", "VIP1 PortA", "VIP1 PortB",
};
char *gCameraLink_ifName[] = {
" 8-bit", "16-bit", "24-bit",
};
char *gCameraLink_modeName[] = {
"Non-mux Embedded Sync", "Line-mux Embedded Sync",
"Pixel-mux Embedded Sync", "Non-mux Discrete Sync",
};
输入方式有hdmi ,sdi,vga, 输出有dvo0(vout1) dvo1(vout0) ,

HDVPSS模块即High-Definition Video Process Sub System,主要用于视频的capture、deinterlacing、scaler、up/down sample、graphics、display等,由Media Controller Dula ARM Cortex-M3系统中的VPSS-M3控制。软件工程师在做程序的时候需要注意各个模块支持数据的输入格式和输出格式(另外需要注意的是:TI提供的RDK中限定了display controller的矩阵连接,如果希望灵活使用这个矩阵连接,需要自行拆分,关于该部分内容请参考HDVPSS_UserGuide.pdf中Display Controller Driver中Macro Mapping)。HDVPSS整体硬件框架如下图所示,注意数据格式。
