Abstract
In an embodiment, a processor includes a first power rail, a first component coupled to the first power rail, and a compensation control unit. The compensation control unit is to: detect a request to change a voltage level of the first power rail by a first voltage change amount; in response to detecting the request, determine that the first voltage change amount exceeds a first threshold level associated with the first component; and in response to determining that the first voltage change amount exceeds the first threshold level, initiate a first compensation action prior to changing the voltage level of the first power rail. Other embodiments are described and claimed.
