Abstract: A system can include multiple content ingress sites to process content into portions of content. A content ingress site, of the multiple content ingress sites, can include a first set of devices. The first set of devices can be configured to process the content in a synchronized manner. The first set of devices can be configured to have excess processing capacity to facilitate failover of a first segmenter device to a second segmenter device. The first set of devices can be configured to process content from multiple sources. The system can include multiple content distribution sites to encode the portions of content. A content distribution site can include a second set of devices. The system can include multiple content satellite offices to provide the portions of content to one or more destination devices. A content satellite office can include a third set of devices.

Abstract: Embodiments of the invention describe arbitrating requests received from a plurality of agents for memory. Each memory request may indicate a priority level of the memory request and a size of the memory to be accessed. Said requests may be stored in a queue. Arbitration logic, coupled to the plurality of agents and the queue, may receive said memory requests and determine which requests to send to the queue based, at least in part, on the priority of each request and the size of the memory to be accessed by each memory request.

Abstract: A scalable, two-stage rotating priority arbiter with re-circulation and bounded latency for use in multi-threaded, multi-processing devices. An apparatus implementing the two-stage arbiter includes a plurality of masters configured in a plurality of clusters, a plurality of targets, and an chassis interconnect that may be controlled to selectively connects a given master to a given target. The chassis interconnect includes multiple sets of bus lines connected between the plurality of clusters and the plurality of targets forming a cross-bar interconnect, including sets of bus lines corresponding to a command bus. A two-stage arbitration scheme is employed to arbitrate access to the command bus. The first arbitration stage is used to arbitrate between target requests issued by masters in a given cluster. The second arbitration stage is used to arbitrate between winning first-stage target requests. One embodiment of the arbitration scheme employs a rotating priority arbitration scheme at the first stage.
