System And Method For Communicating Device Information Between A Device And A Controller

US Patent:
6880076, Apr 12, 2005
Filed:
Jun 29, 2001
Appl. No.:
09/895062
Inventors:
Robert J. Greiner - Beaverton OR,
Matthew Ma - Portland OR,
Edward P. Osburn - Folsom CA,
Michael Stapleton - Portland OR,
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
G06F015/177
US Classification:
713 1, 713100, 713300, 713400, 713500, 713600, 709221, 709222, 709232, 709400
Abstract:
Embodiments of the present invention describe a system and method for microprocessor power regulation. An appropriate amount of voltage is provided to a microprocessor based on a voltage identifier (VID) received by a voltage controller from the microprocessor via a serial communication line. A voltage identifier clock signal (VIDClock) is used for the timing of transmission and receipt of data/acknowledgement signals. A guard clock signal (VIDGuard) is provided via a separate guard clock line to prevent potential noise on the clock line from causing a clock signal misidentification, which could cause a wrong value to be received as the VID. VIDGuard is analyzed in relation to ViDClock to verify the value of the clock signal. To verify receipt of the VID data, a voltage identifier acknowledgement line (VIDAck) is transmitted from the voltage regulator to the microprocessor. The acknowledgement signal is checked by a two-part receipt verification, high-to-low and low-to-high.

Dynamic Voltage Transitions

US Patent:
7444524, Oct 28, 2008
Filed:
Dec 30, 2002
Appl. No.:
10/334966
Inventors:
Stephen H. Gunther - Beaverton OR,
Robert Greiner - Beaverton OR,
Matthew M. Ma - Portland OR,
Kevin Dai - San Jose CA,
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
G06F 1/26
G06F 1/32
US Classification:
713300, 713310, 713320, 713321, 713322, 713323, 713324, 713330, 713340
Abstract:
The operating voltage of an integrated circuit (e. g. , a processor) is changed in response to one or more conditions (e. g. , a laptop computer is connected to an AC power source). Both the operating frequency and the operating voltage of the integrated circuit are changed. The voltage regulator providing the operating voltage to the integrated circuit is caused to transition between voltage levels using one or more intermediate steps. The integrated circuit continues to operate in the normal manner both at the new voltage and throughout the voltage transition.
