Abstract: A system for implementing an augmented reality (AR)/virtual reality (VR) display includes a hardware (HW) architecture that employs a system-on-chip (SoC) to compose and submit textures. The SoC composes and submits textures by using display serial interface (DSI) display lines to transmit the textures to a physical display. Software (SW) architecture includes a stack display architecture with an applications level using the surface rendered by applications, a display service level to compose superframes, provide an abstraction layer on top of a surface flinger (SL) application programming interface (API), and allow assignment of textures and metadata to different hardware planes, and a driver level. The system uses the surfaces or enhanced effects that are rendered by the applications or the compositor, depending on the type of the application, and computes the metadata related to the location or coordinates.
