Appeal No. 1998-0882
Application 08/598,416
The invention relates to a high speed image
processing system. In particular, a processor processes a
source image in sequential portions or slices. Source image
pixels are fetched from the host memory and stored in pixel
buffers. Pixels stored in the pixel buffers are resampled and
transformed. The pixel fetching process from the source
memory and the pixel buffer’s resampling operation are
performed simultaneously. While a new pixel row is fetched
from the source memory, the previous two rows stored in the
pixel buffers are processed. The transformed pixels are then
transferred to a pixel display memory for display.
Representative independent claim 1 is reproduced as
follows:
1. A single image processor apparatus for
transforming an image comprising:
a) within said single image processor, a first
means for transferring image pixel data from a memory to a
temporary storage a portion of image pixel data at a time;
b) said means, within said single image processor,
for sampling each temporarily stored portion of said image
pixel data, wherein the first means for transferring includes
transferring a portion of image pixel data while the means for
sampling is concurrently sampling a previously transferred
portion of image pixel data;
