Abstract
Described embodiments provide a media controller for servicing contexts corresponding to data transfer requests from host devices. The media controller includes a context generator for generating contexts corresponding to the data transfer requests and a buffer for storing one or more context pointers, each pointer corresponding to a context and an action by a system module associated with the context. A context processor is configured to complete a context when the action by a media controller module associated with the context is complete, remove each pointer from the buffer associated with the completed context, and determine whether an interrupt corresponds to the completed context and removed pointer. If no interrupt corresponds to the completed context, the completed context is cleared. If an interrupt corresponds to the completed context, the interrupt is provided to a master processor and a completed context recycler for recycling the completed context pointer to the context generator.
