DSI (Display Serial Interface) defines protocol between host processor and a peripheral such as Display device, based on MIPI Alliance specifications for mobile devices interfaces, which operates with pixels and command sets specified in the DPI-2, DBI-2 and DCS standards. Its purpose is to send pixels and commands to the peripheral such as Display and receives back pixel or status information from the peripheral.
We have selected ARM's AHB bus for the configuration and input video data streaming of our DSI solution, due to its performance and wide market acceptance. Based on customer requests, we are also supporting AMBA's AXI high-performance bus as an alternative SoC bus.
