    摘要: In one embodiment, a processor includes a core with a front end unit, at least one execution unit, and a back end unit. Multiple voltage drop detectors can be located within the core each to output a voltage drop signal when a detected voltage falls below a threshold voltage. In turn, a current transient logic coupled to receive the voltage drop signals can control a micro-architectural parameter of at least one of the front end unit, execution unit and back end unit responsive to receipt of a voltage drop signal. Other embodiments are described and claimed.
