  • Methods for Real-Time Power Analysis in System Simulation
    Publication number: 20180075174
    Abstract: A system simulation runs in addition to a standard simulator a power estimation block which uses the instrumented representation of the system and live data from the standard simulator to compute power consumption and then to display this on a GUI.

  • Dynamic power limit sharing in a platform
    Patent number: 9557804
    Abstract: A method and apparatus for dynamic power limit sharing among the modules in the platform. In one embodiment of the invention, the platform comprises a processor and memory modules. By expanding the power domain to include the processor and the memory modules, dynamic sharing of the power budget of the platform between the processor and the memory modules is enabled. For low-bandwidth workloads, the dynamic sharing of the power budget offers significant opportunity for the processor to increase its frequency by using the headroom in the memory power and vice versa. This enables higher peak performance for the same total platform power budget in one embodiment of the invention.

  • Method, apparatus, and system for energy efficiency and energy conservation including dynamic control of energy consumption in power domains
    Patent number: 9141166
    Abstract: An apparatus, method and system is described herein for dynamic power control of a power domain. A power limit over a time window is provided. And over a control loop period a power interface determines energy consumption of the power domain, intelligently budgets power among devices within the power domain based on the energy consumption, converts those budgets to performance maximums for the power domain, and limits performance of devices in the power domain to the performance maximums utilizing a running average power limit.
