    Abstract: An interrupt delivery mechanism for a system includes and interrupt controller and a plurality of cluster interrupt controllers coupled to respective pluralities of processors in an embodiment. The interrupt controller may serially transmit an interrupt request to respective cluster interrupt controllers, which may acknowledge (Ack) or non-acknowledge (Nack) the interrupt based on attempting to deliver the interrupt to processors to which the cluster interrupt controller is coupled. In a soft iteration, the cluster interrupt controller may attempt to deliver the interrupt to processors that are powered on, without attempting to power on processors that are powered off. If the soft iteration does not result in an Ack response from one of the plurality of cluster interrupt controllers, a hard iteration may be performed in which the powered-off processors may be powered on.

    Abstract: Systems, apparatuses, and methods for implementing telemetry push aggregation techniques are described. A computing system includes one or more input/output (I/O) agents interposed between functional units and a communication fabric. A given I/O agent receives a set of aggregation rules from a power management unit. The I/O agent monitors traffic from the functional units, and the I/O agent generates telemetry data from the traffic data based on the set of aggregation rules. The telemetry data is used by the power management unit to make adjustments to one or more power settings.

    Abstract: A temperature control apparatus is disclosed. An integrated circuit (IC) includes a plurality of temperature sensors, a first thermal control loop, and a second thermal control loop. The first thermal control loop is configured to control temperature of the IC by reducing a frequency of a clock signal provided to the IC in response to a temperature at one of the plurality of temperature sensors reaching a first temperature threshold. The second thermal control loop is configured to control temperature of the IC by dithering the clock signal provided to the IC in response to a temperature at one of the plurality of temperature sensors reaching a second temperature threshold that is greater than the first temperature threshold.

    Abstract: Various techniques and circuit implementations for power reduction management in integrated circuits are disclosed. Certain techniques include the implementation of rate control circuits to control a clock rate for circuits associated with a communication fabric in an integrated circuit. The clock rate may be reduced based trigger signals received from power delivery trigger circuits coupled to the integrated circuit and voltage regulators providing power to the integrated circuit. Additional techniques may include the use of rate limiter circuits in a memory pipeline.
