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.

摘要： In one embodiment, the present invention includes a processor having multiple domains including at least a core domain and a non-core domain that is transparent to an operating system (OS). The non-core domain can be controlled by a driver. In turn, the processor further includes a memory interconnect to interconnect the core domain and the non-core domain to a memory coupled to the processor. Still further, a power controller, which may be within the processor, can control a frequency of the memory interconnect based on memory boundedness of a workload being executed on the non-core domain. Other embodiments are described and claimed.
