Graphics multi-media IC and method of its operation

摘要

A graphics multi-media integrated circuit (GMIC) is connected to a host processor over two serial links: a half duplex bi-directional serial link which accords to a display serial interface protocol, and a uni-directional serial link which accords to a camera serial interface protocol. The GMIC receives packets from the host over the half duplex bi-directional serial link and processes these packets. The GMIC sends packets over the uni-directional serial link. A packet from the host can request a processing operation by the GMIC or can initiate a memory operation at the memory of the GMIC. The GMIC can also send packets to the host to initiate a host memory operation and may be connected to a display over a bi-directional serial link and to a camera over a uni-directional serial link and a bi-directional control link allowing the host to control the display and camera.

主权项

1. A method of communicating at a graphics multi-media integrated circuit comprising:
receiving data packets compatible with a display serial interface packet protocol from a host over a first half duplex bi-directional serial link, said packets containing instructions for a processing module of said graphics multi-media integrated circuit; processing packets from said host in accordance with said instructions at said processing module; sending data packets compatible with a camera serial interface packet protocol toward said host over a first uni-directional serial link.
