Abstract
An improved system and method are provided for initializing memory in a data processing system. According to one aspect of the invention, a “page zero” instruction is provided that may be executed by an Instruction Processor to initiate memory initialization. Upon instruction execution, the IP issues one or more page zero requests using a background interface of the IP. In one embodiment, each request results in the initialization of a page of memory. While page zero requests are issued over the background interface, the IP may continue issuing other read and write requests to memory over a primary interface of the IP.
