Abstract: Hierarchical power estimation and throttling in a processor-based system in an integrated circuit (IC) chip, and related power management and power throttling methods are disclosed. The IC chip includes a processor as well as integrated supporting processing devices for the processor. The hierarchical power management system controls power consumption of devices in the IC chip to achieve the desired performance in the processor-based system based on activity power events generated from local activity monitoring of devices in the IC chip. To mitigate the delay in the reporting of activity power event of a monitored processing device that may affect throttling of power consumption for the IC chip, the power consumption of a monitored processing device can also be throttled locally throttle its power consumption. This gives reaction time for the power management system to receive and process activity power events to throttle power consumption in the IC chip.

Abstract: A throttle management circuit is configured to receive throttle request(s) from at least one state detection circuit, generate and store a throttle recommendation in each clock cycle based on the received throttle request(s), and generate a throttle control signal to throttle activity of processing circuits based on a recent and stored throttle recommendation. The throttle requests may be based on measures of electric states, thermal states, and/or activity states among the processing circuits monitored by the LAM circuit and the measured states may be caused by activity of the processing circuits. The throttle management circuit can provide a local, dynamic, low-latency response to mitigate harm that could otherwise be caused by the measured local states of the processing circuits while waiting for a response from the power management hierarchy. In some examples, the throttle recommendation generated in each cycle affects the throttle control signal for a plurality of subsequent cycles.

Abstract: The processor-based system includes a throttle request accumulate circuit to receive throttle requests, determine a highest or most aggressive throttle value among the throttle requests, and generate a throttle control signal configured to throttle activity in the plurality of processing circuits. Throttle requests have throttle values corresponding to a reduction in activity in at least a portion of the plurality of processing circuits and may correspond to a particular number of cycles of reduced activity in a window of cycles. In addition to reducing response time to local events or conditions compared to waiting for a hierarchical response, the throttle request accumulate circuit accumulates throttle requests from all circuits that adjust or throttle activity in the plurality of processing circuits, and ensures that the net effective throttle controlling activity in the processing circuits at any given time is based on the highest throttle value of those accumulated throttle requests.

Abstract: A throttle control circuit receives a throttle control signal for controlling power consumption in a plurality of processing segment circuits. The throttle control signal has a throttle control value based on throttle requests from monitoring circuits that have detected power-related events or conditions and correspond to a requested change in activity in the plurality of processing segment circuits. The throttle control circuit receives the throttle control signal in a plurality of throttle administration circuits that each generates a throttle select signal to select an activity control signal for a corresponding processing segment circuit. In each of a first number (N) of consecutive cycles of a clock signal, the activity control signal disables state changes in the corresponding processing segment circuit for a second number (M) of cycles among the first number (N) of consecutive cycles to reduce power consumption in the processing segment circuits.

The IC chip includes a processor as well integrated supporting processing devices for the processor. The hierarchical power management system controls power consumption of devices in the IC chip to achieve the desired performance in the processor-based system based on activity power events generated from local activity monitoring of devices in the IC chip. The hierarchical power management system includes a centralized power estimation and limiting (PEL) circuit that is configured to track and merge received power throttle recommendations associated with related activity power events for monitored processing devices to generate one or more power limiting management responses to throttle power consumption of related devices that may be contributing to excess power consumption.

Abstract: Broadcasting power limiting management responses in a processor-based system in an integrated circuit (IC) chip is disclosed herein. In one aspect, an IC chip comprises a processor-based system that includes a power estimation and limiting (PEL) circuit, a Limit Management Throughput Throttle (LMTT) source circuit, a plurality of activity management (AM) circuits, and an LMTT bus communicatively coupling the LMTT source circuit with each AM circuit of the plurality of AM circuits. The LMTT source circuit receives a power limiting management response from a PEL circuit via a communications network of the processor-based system, and generates an LMTT command based on the power limiting management response. The LMTT source circuit broadcasts the LMTT command to each AM circuit of the plurality of AM circuits via the LMTT bus.
