Abstract
A data processing apparatus 2 includes processing circuitry 4 performing processing operations which move the processing circuitry 4 between logical states. Monitoring circuitry 18 monitors logical state variables of the processing circuitry and these are supplied to prediction circuitry 30 which detects predetermined patterns within the logical states which are indicative (previously correlated with) of a future potential temporary insufficiency in the supply power to the processing circuitry 4. When such a pattern is detected, then power control circuitry 8,10 serves to trigger a mitigation response to counteract the future potential temporary insufficiency in power supply, such as temporarily reducing the clock frequency and/or boosting the supply voltage.
