Abstract: A processor may include a core and an uncore area. The power consumed by the core area may be controlled by controlling the Cdyn of the processor such that the Cdyn is within an allowable Cdyn value irrespective of the application being processed by the core area. The power management technique includes measuring digital activity factor (DAF), monitoring architectural and data activity levels, and controlling power consumption by throttling the instructions based on the activity levels. As a result of throttling the instructions, throttling may be implemented in 3rd droop and thermal design point (TDP). Also, the idle power consumed by the uncore area while the core area is in deep power saving states may be reduced by varying the reference voltage VR and the VP provided to the uncore area. As a result, the idle power consumed by the uncore area may be reduced.

Abstract: Systems and methods are provided that can be utilized to estimate power associated with a circuit design. The estimated power is determined by employing power characterizations to determine power consumption associated with non-conventional circuits in the circuit design. The power characterizations can be determined prior to circuit design timing analysis, stored and utilized during circuit design timing analysis. The power estimates associated with the non-conventional circuits can be added to power estimates associated with the conventional circuits of the circuit design to compute a power associated with the circuit design.

A waveform control provides a control output that temporarily adjusts to an intermediate level between normal high and low levels during a first operating mode. The waveform control provides the control output to transition periodically between the high and low levels during a second operating mode. A delay network controls the waveform control to provide the output at the intermediate level for a duration during the first operating mode.

Abstract: The invention provides a method and circuit for measuring on-chip, cycle-to-cycle, jitter. Copies of a circuit comprising a programmable delay line, a programmable phase comparator, and two counters are placed at different locations on an IC near a clock signal. The programmable delay line creates a clock signal that is delayed by one clock cycle. This delayed clock signal is compared in time to the original clock signal by the programmable phase comparator. If the difference in time between the delayed clock signal and the clock signal is greater than the dead time, the first counter is triggered. If the difference in time is negative and the absolute value is greater than the dead time, the second counter is triggered. A statistical distribution, based on the values of the counters, is created. This distribution is used to predict on-chip, cycle-to-cycle jitter.
