摘要： An apparatus may comprise one or more processor cores of a processor and a set of current limiters. Each current limiter may be coupled to a respective processor core and arranged to monitor processor activity in the processor, to compare the processor activity to one or more current limits of multiple current limits; and to initiate a current-limiting action when the one or more current limits is exceeded.

摘要： In one embodiment, the present invention includes a method for determining, in a controller of a multi-domain processor, whether a temperature of a second domain of the multi-domain processor is greater than a sum of a throttle threshold and a cross-domain margin, and if so, reducing a frequency of a first domain of the multi-domain processor by a selected amount. In this way, a temperature of the second domain can be allowed to reduce, given a thermal coupling of the domains. 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.

摘要： In one embodiment, the present invention includes a multicore processor with a power controller to control a frequency at which the processor operates. More specifically, the power controller can limit a maximum operating frequency of the processor to less than a configured maximum operating frequency to enable a reduction in a number of frequency transitions occurring responsive to power state events, thus avoiding the overhead of operations performed in handling such transitions. Other embodiments are described and claimed.
