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 IoT application processor
functional specification.
