Graphics processor trapezoidal fill instruction method and apparatus.

摘要

There is disclosed a graphic processing system (100) which contains a microcoded control processor (120) for creating, under command of the main graphic processor (110), the fill data necessary for presenting graphic objects to a display medium The graphic processor (110) transfers to a microcoded process and circuit (120) the begin and end points of certain basic object shapes, and the microcoded process and circuit (120) thereupon calculates all of the remaining points within the confines of the presented shape. Provision is made for handling slopes of any value
