Abstract
In a preferred embodiment, a system includes a host, an image data source, and a graphics controller. The image data source provides a frame corresponding to a particular image size. The graphics controller is receives the frame. Preferably, the graphics controller is remote from the image data source and the host, and includes a fitting module for calculating a scale factor based on the image size, and a scaling unit for scaling the image according to the scale factor. In another preferred embodiment, a system includes a display device of a particular resolution, a memory, and a graphics controller. The memory is for storing a frame corresponding to a particular image size. The graphics controller preferably includes: a fitting module for calculating a scale factor based on the image size and the display device resolution, and a scaling unit for scaling the image according to the scale factor. The graphics controller may be adapted for retrieving the display device resolution from the display device. Preferred embodiments prevent the host from being repeatedly interrupted each time a new frame needs to be stored or written to the display device thereby improving host and system efficiency.
