Abstract
Some aspects of this disclosure relate to a peak power manager that includes a first power estimate accumulator circuit configured to receive one or more power estimates associated with one or more subsystems and to generate a first accumulated power estimate. The peak power manage can further include a first-in first-out (FIFO) storage circuit configured to store a plurality of first accumulated power estimates associated with a plurality of clock cycles corresponding to a moving time interval window. The peak power manager can further include a second power estimate accumulator circuit configured to accumulate the plurality of first accumulated power estimates to generate a second accumulated power estimate and a control circuit. The control circuit can be configured to compare the second accumulated power estimate with a threshold power and generate a control signal to control one or more events at the one or more subsystems in response to the second accumulated power estimate satisfying a condition associated with the threshold power.
