ABSTRACT:
A graphics controller circuit for converting a plurality of monochrome pixel data into a corresponding set of color pixel data in RGB 888 format. The graphics controller circuit packs the converted color pixel data into a plurality of 64-bit color pixel words, with each color pixel word comprising two complete color pixel words and portion of at least one another color pixel word. By having color pixel data cross word boundaries, graphics controller of the present invention optimally stores color pixel data in color pixel words. The graphics controller circuit further includes a half-word addressable split-RAM which enables continuous availability of subsets of monochrome pixel data during each clock cycle for conversion to color data.
