  • Calibrating power supply voltages using reference measurements from code loop executions
    Patent number: 10060955
    Abstract: A processing system includes one or more power supply monitors (PSMs) to measure one or more first voltages corresponding to one or more locations in the processing system. The measurements are performed concurrently with the processing system executing one or more code loops. The processing system also includes calibration logic to modify a second voltage provided to the processing system based on a comparison of a reference voltage and the one or more first voltages. The reference voltage is determined based on previous execution of the one or more code loops by the processing system.

  • Configurable computer system
    Publication number: 20080114918
    Abstract: A method for providing multiple configurations for a computer system. The method provides interconnection of processor boards in a first configuration and a second configuration. In the first configuration, a first plurality of processor boards are interconnected through a first backplane. In a second configuration, a second plurality of processor boards are interconnected through a second backplane. The first and second pluralities of processor boards are interchangeable with each other.

  • Method of preventing computer malfunction during a change of power consumption states via dynamic adjustment of core voltage
    Patent number: 6523129
    Abstract: An improved method of preventing computer malfunction during a change of power consumption states is disclosed. The computer operates a microprocessor at a specified voltage during a normal operation. To offset the normal decrease in voltage due to an instantaneous increase in power requirements during a change of power consumption states, the specified voltage is increased prior to entering a higher power consumption state such that the voltage level remains within minimum operating limits.
