Multimedia subsystem (MMsys) contains multimedia controller, Multimedia Data Path v2.0 (MDP 2.0) and Display (DISP). The multimedia controller includes bus fabric control, Smart Memory Interface (SMI) control, memory access second-level arbiter, and multimedia configuration. It plays the key role in handling different handshakings between infra subsystem, video subsystem, image subsystem and G3D subsystem. For more detail, ask Mediatek for the MT8365 AIoT application processor functional specification.
