ABSTRACT:
An apparatus and a method of encoding a dirty bit within plural bit control data for controlling an operation by a computer graphics system to simultaneously indicate reset or clear of data for a pixel in the system to quickly update a frame on a screen in an animation application are disclosed. Flexibility of the encoding dirty bits and a trade-off among a relative size of a set of control data available for the system to control the operation are easily achieved by the apparatus and the method.
