Mini-DSI Panel Video Output
The design receives video stream from the Raspberry Pi camera through a MIPI CSI RX
block, then displays the video on the Mini-DSI panel through a MIPI DSI TX block. A
Sapphire RISC-V SoC controls the operation flow of the design and assigns the DMA
controller to stream video frame data to and from the HyperRAM.
UVC Video Output
The design streams the video to the computer through USB. The design sends video signal
in YUV2 format to the USB 3.0 controller. Then the USB 3.0 controller streams it to the
computer in UVC framework. The video can be displayed on standard computer camera
software, for example, the Windows 10 Camera App.
