Throttle control circuits for throttling activity in processing segment circuits in an integrated circuit (ic) chip and related methods

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.
