Abstract

A memory interface unit is described having a first interface to receive a first request from a processor where the first request has an attribute. The memory interface unit also has a second interface to receive a second request from the processor where the second request does not have the attribute. The memory interface unit also has a third interface to read/write information from/to a system memory. A method is also described that involves forwarding a processor request along a first path to a memory interface unit if the request has one or more attributes; and forwarding the request along a second path to the memory interface unit if the processor request does not have the one or more attributes.
