  • Publication number: 20190011976
    Abstract: Methods and apparatus relating to autonomous C state mechanism and computational engine alignment for improved processor power efficiency. are described. An embodiment determines whether a semiconductor package should enter a package C state based on energy consumption values for entry into and exit from the package C state, an amount of time the semiconductor package stayed in the package C state previously, and one or more breakeven time points between the various package C states. Another embodiment detects a delay by an imaging computational unit of a processor to enter a low power consumption state relative to one or more other computational units of the processor. The logic causes the imaging computational unit to enter the low power consumption state in response to detection of the delay. Other embodiments are also disclosed and claimed.

  • Publication number: 20170285703
    Abstract: In an embodiment, a processor includes a first core and a power management agent (PMA), coupled to the first core, to include a static table that stores a list of operations, and a plurality of columns each to specify a corresponding flow that includes a corresponding subset of the operations. Execution of each flow is associated with a corresponding state of the first core. The PMA includes a control register (CR) that includes a plurality of storage elements to receive one of a first value and a second value. The processor includes execution logic, responsive to a command to place the first core into a first state, to execute an operation of a first flow when a corresponding storage element stores the first value and to refrain from execution of an operation of the first flow when the corresponding element stores the second value. Other embodiments are described and claimed.

  • 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.
