Abstract: An embodiment of a system may include a plurality of media units, a processor, and circuitry. Each media unit may be configured to execute one or more commands to process a display image. The processor may be configured to store a plurality of media processing commands in a queue. The circuitry may be configured to retrieve a first media processing command from the queue and send the first media processing command to a first media unit. The circuitry may also be configured to retrieve a second media processing from the queue and send the second media processing command to a second media unit in response to receiving an interrupt from the first media unit. The circuitry may then copy data from the first media unit to the second media unit in response to receiving the interrupt from the first media unit.

Abstract: A method and apparatus for dynamic clock and power gating and decentralized wakeups is disclosed. In one embodiment, an integrated circuit (IC) includes power-manageable functional units and a power management unit. Each of the power manageable functional units is configured to convey a request to enter a low power state to the power management unit The power management unit may respond by causing a requesting functional unit to enter the low power state. Should another functional unit initiate a request to communicate with a functional unit currently in the low power state, it may send a request to that functional unit. The receiving functional unit may respond to the request by exiting the low power state and resuming operation in the active state.

Abstract: In some embodiments, a system includes a shared, high bandwidth resource (e.g. a memory system), multiple agents configured to communicate with the shared resource, and a communication fabric coupling the multiple agents to the shared resource. The communication fabric may be equipped with limiters configured to limit bandwidth from the various agents based on one or more performance metrics measured with respect to the shared, high bandwidth resource. For example, the performance metrics may include one or more of latency, number of outstanding transactions, resource utilization, etc. The limiters may dynamically modify their limit configurations based on the performance metrics. In an embodiment, the system may include multiple thresholds for the performance metrics, and exceeding a given threshold may include modifying the limiters in the communication fabric. There may be hysteresis implemented in the system as well in some embodiments, to reduce the frequency of transitions between configurations.

Abstract: In an embodiment, one or more fabric control circuits may be inserted in a communication fabric to control various aspects of the communications by components in the system. The fabric control circuits may be included on the interface of the components to the communication fabric, in some embodiments. In other embodiments that include a hierarchical communication fabric, fabric control circuits may alternatively or additionally be included. The fabric control circuits may be programmable, and thus may provide the ability to tune the communication fabric to meet performance and/or functionality goals.
