1. An apparatus comprising:
a plurality of components;
a first sensor to measure first power consumed by first one or more components of the plurality of components;
a second sensor to measure second power consumed by the apparatus;
an analog-to-digital converter (ADC) to generate an identification (ID) that is representative of the second power consumed by the apparatus; and
a controller to allocate power budget to one or more components of the plurality of components, based on the measurement of the first power and the ID, wherein a power spike is detected if the second power consumed by the apparatus is higher than a threshold value and wherein the ADC is to issue a first power event alert to the controller in response to the power spike being sensed, wherein the ADC is bypassed if the second sensor issues a second power event alert to the controller if the second sensor senses the power spike,
wherein the ADC is to:
receive an analog signal from the second sensor, the analog signal being representative of the second power consumed by the apparatus; and
detect, prior to a completion of an analog-to-digital conversion of the measurement of the analog signal, that the analog signal is higher than the threshold value by sensing one or more most significant bits of an output of the ADC.
