Abstract
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.
