Abstract
A graphics controller for animating an overlay is described. The graphics controller includes a host interface for communicating with an external processor and a plurality of registers in communication with the host interface. Logic is configured to periodically change coordinates of an overlay image. The logic responds to values stored in the registers to cause display registers containing the coordinates to be updated every x number of frame refreshes, wherein x is a positive integer.
