Abstract

A memory management system and method are described. In one embodiment, a memory management system includes a memory management unit for virtualizing context memory storage and independently controlling access to the context memory without interference from other engine activities. The shared resource management unit overrides a stream of access denials (e.g., NACKs) associated with an access problem. The memory management system and method facilitate access to memory while controlling translation between virtual and physical memory “spaces”. In one embodiment the memory management system includes a translation lookaside buffer and a fill component. The translation lookaside buffer tracks information associating a virtual memory space with a physical memory space. The fill component tracks the status of an access request progress from a plurality of engines independently and faults that occur in attempting to access a memory space.
