The Application Example Design demonstrates the usage of the MIPI CSI-2 RX Subsystem and MIPI DSI TX Subsystem on Spartan -7 SP701 board. On the capture path, the system receives images captured by pcam-5c image sensor. Processed images are displayed on either the HDMI monitor or MIPI DSI Display.

The MIPI CSI-2 RX Subsystem decodes, processes video data and presents on AXI4-Stream data with two pixels data per clock. The RAW video data is then converted into RGB data using the Demosaic IP two pixels at a time. The AXI4-Stream data is sent to the AXI Switch that broadcast the stream to MIPI DSI TX Subsystem or the AXI4 Stream to Video Out Subsystem depending on the user selection.

The Video Test Pattern Generator IP (V-TPG) is available in the HDMI Path to act as an alternate source of video in case no MIPI CSI-2 video source is present. The TPG (in pass-through mode) sends video packets across to the AXI4 Stream to Video Out.

If the MIPI DSI TX Subsystem path is chosen, the video is passed through a video processing subsystem configured as a Scaler. This is required as the MIPI DSI Panel works on a fixed resolution of 1920x1200. The video must be up scaled (1080p) to 1920x1200 resolution for the MIPI DSI display panel.
