IQ-DSI-Rx is a MIPI DSI protocol engine/ receiver IP core designed to work with PPI-compatible MIPI D-PHY serial interfaces for driving embedded displays.

MIPI DSI Receiver IP core (IQ-DSI-Rx) together with the DPHY-Rx IP core provides the capability to receive MIPI DSI compliant traffic from a DSI host processor, and to decode received DSI video mode packets as video data.

MIPI DSI Receiver receives DSI packets from the MIPI D-PHY IP core through the PHY Protocol Interface (PPI) recommended by the MIPI Alliance. The received packets are then decoded and converted to the standard parallel video interface. A couple of additional diagnostic capabilities are available to help with identifying the format of the incoming DSI stream. The IP core can be controlled over the Avalon-MM interface.
