An apparatus and a method for optimizing data streaming in a computer
system utilizing random access memory in a system logic device have been
presented. In one embodiment, the apparatus includes a processor
interface unit and a cache to store information received from a processor
coupled to the processor interface unit, the cache to store disposable
information that may be overwritten without ever having delivered the
disposable information to a system memory if the disposable information
has been read at least once, the processor interface unit to receive a
disposable information attribute indication from the processor when the
processor delivers the disposable information to the processor interface
unit.
