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.

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.

摘要： A memory access technique, in accordance with one embodiment of the present invention, includes caching segmentation data. The technique utilizes a separate memory for storing a plurality of context specifiers and an MMU. The MMU includes an on-chip cache and a segmentation unit. The MMU receives a location of a particular context specifier and a corresponding context index for each of one or more of the plurality of context specifiers stored in the separate memory. The segmentation unit retrieves the particular context specifier and caches it locally. The segmentation unit also binds the cache location of the particular context specifier to the corresponding context index. After caching one or more context specifiers and generating a corresponding binding, the segmentation unit may receive a memory access request that includes a given context index. A given context specifier that is cached locally is accessed by the segmentation unit using the context index to get a base address. The base address from the given context specifier is utilized by the segmentation unit to generate a virtual address for the memory access request.
