The Arasan DSI Device Controller IP is designed to provide MIPI compliant high speed serial connectivity for mobile display modules with Type 1 to 4 architectures. Serial connectivity to the mobile applications processor’s DSI host 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.
Display modules consist of display driver logic driving display signals onto a display device or panel. On the display driver side, Arasan’s DSI Device Controller provides the DBI Interface for Types 1 to 3 display modules, and the DPI Interface 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.
