Original Abstract Submitted
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.
