  • Patent number: 9541949
    Abstract: In an embodiment, a processor includes a master counter to store a time stamp count for the processor, and multiple cores each including a core counter to store core time stamp counts. The processor also includes synchronization logic to, in response to a de-synchronization event in a core: obtain a value of the master counter; initiate a first core counter using the value of the master counter, where the first core counter is included in the first core; compare a synchronization digit of the first core counter to a synchronization signal indicating a value of a synchronization digit of the master counter; and in response to a determination that the synchronization digit does not match the synchronization signal, adjust a first subset of digits of the first core counter based on a latency value of the synchronization signal. Other embodiments are described and claimed.

  • Patent number: 8032772
    Abstract: With the progress toward multi-core processors, each core is can not readily ascertain the status of the other dies with respect to an idle or active status. A proposal for utilizing an interface to transmit core status among multiple cores in a multi-die microprocessor is discussed. Consequently, this facilitates thermal management by allowing an optimal setting for setting performance and frequency based on utilizing each core status.

  • Patent number: 6331957
    Abstract: An integral breakpoint detector. The integral breakpoint detector may be included in a processor, a chipset, or another bus agent. One embodiment is an apparatus such as an integrated circuit that includes a bus interface to communicate with a bus and an integrated breakpoint detector. The bus interface may include a bus tracker which communicates with the integrated breakpoint detector. The integrated breakpoint detector is to provide a first indication responsive to an occurrence of a predetermined relationship between a programmable value and a condition related to the bus.
