RK3576 Camera：资源介绍

news 2025/6/20 2:53:43

RK3576是RK今年上市的中高端旗舰芯片，定位弱于RK3588。这篇文章主要分享一下RK3576这颗主控芯片的camera资源。

（1）RK3576 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DCPHY，2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DCPHY，2路DPHY，其中2路DPHY都可以拆成2lane+2lane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/bps，4lane场景，最大带宽为10Gbps，YUV422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。

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：VPSS（Video 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2lane+2lane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：

（2）dts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：
