MIPI VGI for Sideband GPIO and Messaging Consolidation on Mobile System (Qualcomm & Lattice)
Abstract: In a typical mobile influenced system a large number of sideband GPIOs are used which add to package size and cost. FSM based MIPI VGI aims to consolidate these sideband GPIOs and low speed messaging over a 2- or 3-wire interface. VGI FSM could also be used behind a suitable serial interface, such as I3C. MIPI VGI v1.0 spec is nearing its completion and is expected to be released next year.
