ABSTRACT:
The present invention provides a method and apparatus for transferring a video image, to be resized, from a host processor to an accelerator chip of a display adapter such that the storage capacity of a memory device in the chip is greatly reduced. The video data is first divided into MxM arrays of data elements. Then, the arrays are transferred one row at a time. Each row is stored before being processed by the chip. Consequently, since these rows are much shorter than the lines of frames of data elements, the storage capacity of the chip's memory device is greatly reduced.
