1RK3576 camera资源
①RK3576 camera硬件框图
RK3576的camera硬件框图如图所示拥有一路4lane的DCPHY2路4lane的DPHY可以拆分成4路2lane的模式还有一路DVP并口可以支持BT1120/BT656/BT601接口视频数据。有一个ISP控制器。 ②MIPI-CSI资源
RK3576 MIPI-CSI资源如下有1路DCPHY2路DPHY其中2路DPHY都可以拆成2lane2lane的模式使用共计5个MIPI-CSI HOST可支持接入5个MIPI camera设备2lane的场景最大带宽为5G/bps4lane场景最大带宽为10GbpsYUV422的图像输入的话例如HDMIIN转接芯片可以支持到4K60。DCPHY可以作为DPHY 4lane输入也可以作为CPHY 3trios输入CPHY的场景带宽可达到17Gbps。

③VICAP资源
接口数量输入输出vicap 5个MIPI 1个DVP MIPI CSI: RAW8/10/12/14/16, RGB888, YUV422 8bit, YUV422 8bit interlaced, YUV420 8bit, Legacy YUV420 8bit DVPBT.601 RAW8/10/12 YCbCr 422 8-bit input BT.656 YCbCr 422 8-bit progressive/interlaced input BT.1120 YCbCr 422 8-bit progressive/interlaced input NV16/NV12/YUV400/YUYV 紧凑/非紧凑 RAW RGB888
④ISP资源
工作模式吞吐率最大分辨率输入格式单cis 16M30fps 48M10fps 4672x3504 8064x6048 VICAP: raw8/raw10/raw12
⑤VPSS
看RK3576的描述在ISP后级应该还有VPSS模块可以做图像处理但是目前RK官方似乎也没有描述RK3576该模块的功能以及使用方法。以下是网上海思VPSS模块的描述。
根据网上对海思VPSS模块的描述VPSSVideo Process Sub-System支持对一幅输入图像进行统一预处理如去噪、去隔行等然后再对各通道分别进行缩放、锐化等处理最后输出多种不同分辨率的图像。
根据RK的描述应该是可以支持旋转镜像裁减多路输出等功能。 ⑥最多支持camera数量
RK3576最多可以支持5个MIPIcamera一个DVP的camera对应链接框图如下两路DPHY分别使用2lane2lane的方式如果是YUV的sensor仅需要链接到rkcif_mipi_lvds节点即可不需要接到stdif虚拟节点。 若采用4lane的方式链接如下 2dts配置
根据上述RK3576至多可以同时接入5路 MIPI摄像头下篇文章再介绍。可参考如下
