The Arasan DSI Host Controller IP is designed to provide MIPI DSI 1.02 compliant high speed serial connectivity for mobile application processors using 1 to 4 D-PHYs depending on bandwidth needs. Serial connectivity to the display module’s DSI device is implemented using 1 to 4 D-PHY’s (also available from Arasan), depending on display bandwidth needs. This IP connects to the D-PHY’s through the PPI interface.
On the application processor side, Arasan’s DSI Host Controller provides the choice of DPI or DBI Interface to a graphics controller. A DBI interface provides downstream support of Types 1 to 3 display modules, and the DPI Interface is needed for Types 2 to 4 displays.
Initial configuration of this IP can be done through programmed IO over the AHB bus, however, other bus interfaces can be provided upon request.
