摘要： A graphics system utilizes page table entries to provide information on the storage format used to store graphics data. The page table entries, in turn, may be used for address translation. Exemplary kinds of storage format information include compression mode, a packing mode for storing Z data in tiles or color data in tiles, and a mode for allocating tile data among partitions in a partitioned memory.

摘要： A shared memory management system and method are described. In one embodiment, a memory management system includes a memory management unit for coordinating context memory storage block binds and independently controlling access to the context memory without interference from other engine activities. In one exemplary implementation the context information is included in a block and the memory management unit binds the block to instance memory. The instance memory can be protected memory. The instance memory can also support multiple channels associated with the plurality of engines. In one exemplary implementation, the instance memory includes a pointer to a page table. The instance memory can also include context save and restore data and each one of the plurality of engines initiates a unique block bind by indicating an association between their engine ID and a given block of instance memory.

In one embodiment, a memory management system includes a memory management unit for concurrently managing memory access requests from a plurality of engines. The shared memory management system independently controls access to the context memory without interference from other engine activities. In one exemplary implementation, the memory management unit tracks an identifier for each of the plurality of engines making a memory access request. The memory management unit associates each of the plurality of engines with particular translation information respectively. This translation information is specified by a block bind operation. In one embodiment the translation information is stored in a portion of instance memory. A memory management unit can be non-blocking and can also permit a hit under miss.

摘要： 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.
