Abstract:
1. A digital data processing system comprising: a source of data, adapted to provide pixel data representing an image frame line segment, said line segment comprising at least one data block containing pixels arranged in a raster order, wherein the data source is a memory adapted to store image frames and wherein each data block is of fixed size and contains a selectable number of pixels; means for receiving the line segment and selecting pixel values from the line segment, wherein the selected pixels comprise a raster order pixel group; means for constructing a subframe line from the raster order pixel group, said subframe line comprising at least one data word containing at least 2 pixels arranged in a raster order; packing control means to determine the number of pixels comprising each data block; base address control means for specifying the base address of an image frame; means for specifying a pitch of said image frame, the pitch representing the address offset between corresponding pixels of consecutive image frame lines; means for specifying an image frame line number; and means for computing the start address of the image frame line in response to the base address control means, the packing control means, the image pitch, and the image frame line number.
