Abstract
A display processor for displaying data in one or more windows on a display screen. The display processor divides a display screen into a plurality of horizontal strips with each strip further subdivided into a plurality of tiles. Each tile represents a portion of a window to be displayed on the screen. Each tile is defined by tile descriptors which include memory address locations of data to be display in that tile. The descriptors need only be changed when the arrangement of the windows on the screen is changed or when the mapping of any of the windows into the bit-map is changed. The display processor of the present invention does not require a bit map frame buffer to be utilized before displaying windowed data on a screen. Each horizontal strip may be as thin as 1 pixel, which allows for the formation of windows of irregular shapes, such as circles.
