Abstract
Display hardware which manages a plurality, e.g. three, potentially overlapping display windows each having its own pixel values and potentially having its own palette, with no limitation as to the position of the windows relative to each other. This capability is provided at a reduced hardware complexity as compared to a parallel hardware approach, by arranging substantial portions of the hardware in a multiplexed fashion so that the same hardware handles the lookup of palette entries for pixel values, regardless of the currently active window. The hardware is arranged so that it may switch in real time from processing data for one window to processing data for another window, whenever the current display coordinate crosses a window boundary.
