1. A method for controlling a data processing system, comprising:
detecting a droop in a power supply voltage of a functional circuit of the data processing system greater than a programmable droop threshold; and
throttling an operation of the data processing system according to a programmable step size, a programmable assertion time, and a programmable de-assertion time specified by an output of one or more throttle registers in response to detecting said droop.
