US 2006/0066630 A1 · Apparatus and method for transmitting data between graphics controller and external storage

Abstract

A graphics controller and associated method of operation is provided. The graphics controller includes a memory for receiving image data from an image producing source. The graphics controller also includes an image data wrapper module having circuitry that operates independent of a processor external to the graphics controller. The image data wrapper module is configured to read image data from the memory and package the image data with transmission protocol formatting for transmission from the graphics controller to a memory card that is external to the graphics controller. The graphics controller further includes a memory card interface configured to enable transmission of the image data, having been packaged by the image data wrapper module, from the graphics controller to the memory card.
