Multi-graphics processor system, graphics processor and rendering method

摘要

A first GPU is provided with a digital video output terminal (134) (Vout terminal) for connection to an external source. A digital video signal output from the Vout terminal is provided to a display device via a HDMI. The first GPU (100) and a second GPU (200) are connected to each other via a data bus (140) for bidirectional data exchange. The second GPU (200) applies a predetermined rendering process on data provided from the first GPU (100) via a data input and output interface. The rendered data is returned to the first GPU (100) via the data input and output interface. The first GPU (100) processes the data returned from the second GPU (200) as necessary and outputs a digital video signal via the Vout terminal and the HDMI.
