Patents by Inventor Steven D. Gorman

Steven D. Gorman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus to reduce the risk of observation of program operation
    Patent number: 6519721
    Abstract: A method includes first, disabling debug support for a program such that debug support may not be re-enabled for the program until execution of the program by a processor terminates. Second, data signals external to the program are read to determine program operation.
    Type: Grant

  • Method and apparatus providing multiple voltages and frequencies selectable based on real time criteria to control power consumption
    Patent number: 5812860
    Abstract: A method and system for reducing power consumption in a processor core. A state machine is used to coordinate a frequency from a clock signal generator with a voltage from a voltage regulator which is sufficient to allow operation of the processor at that frequency. Both the clock signal generator and the voltage regulator must be able to generate at least two frequencies or voltages, respectively. A level of processor need is tracked and the lowest frequency/voltage pair that will allow the processor core to satisfy the need is selected. The level of processor need is monitored either periodically or continually such that a new frequency/voltage pair can be dynamically selected as the application mix changes.
