The MIPI Camera Serial Interface 3 (CSI-3) is an interface between a Camera and a host processor baseband application engine. This interface, defined by MIPI Alliance, uses Unipro and MPHY for Link and PHY layers respectively. CSI-3 Host is the command decoding and pixel encoding logic between the Camera and UniPro.
GDA’s CSI-3 Device IP supports two C-Ports for pixel data and one C-Port for attribute transfer. In the CSI-3 Device, the pixel data from Camera is subsequently processed before being sent upstream to UniPro. The control flow, being opposite to data flow, is initiated by the application processor, to configure UniPro, and MPHYs downstream in both Host and Device sides, and also CSI-3 Device. The GDA MIPI CSI-3 Device along with GDA MIPI UniPro, MPHY and GDA MIPI CSI-3 Host provide a complete solution for a camera application.
