ABSTRACT:
A method and apparatus for managing overlay data requests are disclosed. One embodiment of an apparatus includes a request unit and a timer. A request is made by a graphics controller to the request unit for a line of overlay data. The request unit divides the request from the graphics controller into a series of smaller requests. The smaller requests are issued to a memory controller. Delays are inserted between each of the smaller requests in order to allow other system resources to more easily gain access to memory.
