Bus structure and method for compiling pixel data with priorities

摘要

A bus structure for coupling pixel data to control a raster-type display of objects that are represented by the pixel data in storage operates in real time to assemble pixel data for each pixel-count interval from the pixel data in a plurality of memory segments that are connected in cascade. Priority of displayable overlapping images is restored by comparing priority data stored with associated pixel data to transfer from memory and along the bus structure the pixel data for a pixel-count interval that has the highest associated priority data.
