Abstract

The invention provides a graphics engine for rendering image data for display pixels in dependence upon received high-level graphics commands defining polygons including an edge draw unit to read in a command phrase of the language corresponding to a single polygon edge and convert the command to a spatial representation of the edge based on that command phrase. An electrical device incorporating the graphics engine and a memory integrated circuit having an embedded graphics engine are also provided.
