In one embodiment, the present invention includes a multicore processor having a variable frequency domain including a plurality of cores and at least a portion of non-core circuitry of the processor. This non-core portion can include a cache memory, a cache controller, and an interconnect structure. In addition to this variable frequency domain, the processor can further have a fixed frequency domain including a power control unit (PCU). This unit may be configured to cause a frequency change to the variable frequency domain without draining the non-core portion of pending transactions. Other embodiments are described and claimed.

A technique for intelligently evicting cache lines within an inclusive cache architecture. More particularly, embodiments of the invention relate to a technique to evict cache lines within an inclusive cache hierarchy based on the cache coherency traffic generated between an upper level cache and lower level caches.

A discussion of a dynamic configuration for a prefetcher is proposed. For example, a thread specific latency metric is calculated and provides dynamic feedback to the software on a per thread basis via the configuration and status registers. Likewise, the software can optionally use the information from the registers to dynamically configure the prefetching behavior and allows the software to be able to both query the performance and configure the prefetcher.

A method and apparatus to monitor architecture events is disclosed. The architecture events are linked together via a push bus mechanism with each architectural event having a designated time slot. There is at least one branch of the push bus in each core. Each branch of the push bus may monitor one core with all the architectural events. All the data collected from the events by the push bus is then sent to a power control unit.

In one embodiment, link logic of a multi-chip processor (MCP) formed using multiple processors may interface with a first point-to-point (PtP) link coupled between the MCP and an off-package agent and another PtP link coupled between first and second processors of the MCP, where the on-package PtP link operates at a greater bandwidth than the first PtP link. Other embodiments are described and claimed.

In one embodiment, the present invention includes a multicore processor having first and second cores to independently execute instructions, the first core visible to an operating system (OS) and the second core transparent to the OS and heterogeneous from the first core. A task controller, which may be included in or coupled to the multicore processor, can cause dynamic migration of a first process scheduled by the OS to the first core to the second core transparently to the OS. Other embodiments are described and claimed.
