The VS_DSI2_Device_Controller is a MIPI-compliant digital controller that resides on the display side of the link, serving as the bridge between the host system and the physical layer. It receives DSI-2 commands and data from the Host Controller Core through 1 to 4 D-PHY or C-PHY lanes, then reassembles the protocol packets for the display pipeline.
This DSI-2 interface IP core is fully compliant with MIPI Alliance Standard for Display Serial Interface 2 (DSI-2) Version 2.2. It supports both D-PHY (up to 4 lanes) and C-PHY (up to 3 trios) interfaces with configurable PPI widths for high-speed and low-power operation. The IP provides an enhanced DPI supporting both video and command modes with programmable signal polarity. It also supports a wide range of video mode formats per DSI-2 v2.2, including various YCbCr, RGB, and compressed pixel streams up to 48-bit. In addition to BIST (color bar) mode, comprehensive error detection is implemented, covering PHY, packet, protocol, and FIFO status.
