Patent number: 11263044Abstract: A graphics processing unit (GPU) adjusts a frequency of clock based on identifying a program thread executing at the processing unit, wherein the program thread is detected based on a workload to be executed. By adjusting the clock frequency based on the identified program thread, the processing unit adapts to different processing demands of different program threads. Further, by identifying the program thread based on workload, the processing unit adapts the clock frequency based on processing demands, thereby conserving processing resources.Type: GrantFiled: November 22, 2019Date of Patent: March 1, 2022Assignees: Advanced Micro Devices, Inc., ATI TECHNOLOGIES ULCInventors: Mangesh P. Nijasure, Michael Mantor, Ashkan Hosseinzadeh Namin, Louis Regniere

Publication number: 20210049030Abstract: The present disclosure relates to techniques for allocating performance counters to virtual functions in response to a request from a respective one of the virtual functions. In response to receiving a request from a respective one of the virtual functions for a performance counter, a security processor is configured to allocate, via a controller, a register associated with a processor to the virtual function, such that the register is configured to implement the performance counter.Type: ApplicationFiled: August 16, 2019Publication date: February 18, 2021Inventors: Louis REGNIERE, Anthony ASARO, Jeffrey G.

Patent number: 10474490Abstract: A technique for efficient time-division of resources in a virtualized accelerated processing device (“APD”) is provided. In a virtualization scheme implemented on the APD, different virtual machines are assigned different “time-slices” in which to use the APD. When a time-slice expires, the APD performs a virtualization context switch by stopping operations for a current virtual machine (“VM”) and starting operations for another VM. Typically, each VM is assigned a fixed length of time, after which a virtualization context switch is performed. This fixed length of time can lead to inefficiencies. Therefore, in some situations, in response to a VM having no more work to perform on the APD and the APD being idle, a virtualization context switch is performed “early.” This virtualization context switch is “early” in the sense that the virtualization context switch is performed before the fixed length of time for the time-slice expires.Type: GrantFiled: June 29, 2017Date of Patent: November 12, 2019Assignees: Advanced Micro Devices, Inc., ATI TECHNOLOGIES ULCInventors: Gongxian Jeffrey Cheng, Louis Regniere, Anthony Asaro

Publication number: 20140339459Abstract: The present invention relates to a method of manufacturing a piezoelectric ceramic body and devices therefrom. The method comprises mixing a piezoelectric ceramic powder with a polymer binder and surfactant to form a slip mixture, casting the slip mixture into a mold and setting to the slip mixture in the mold to form a green body, cutting the green body to form a cut green body with an array of micron-sized ceramic elements and separation, and sintering the cut green body to form a sintered ceramic body. The sintered ceramic body can be further process to encasing in a polymer material to form a piezoelectric ceramic-polymer composite. The piezoelectric ceramic-polymer composite can be further processed to form devices such as acoustic transducers and sensors.Type: ApplicationFiled: April 21, 2014Publication date: November 20, 2014Applicant: SONAVATION, INC.Inventors: De Liufu, Louis Regniere

Publication number: 20120279865Abstract: Provided herein is a method of making an integrated circuit device using copper metallization on 1-3 PZT composite. The method includes providing an overlay of electroplated immersion of gold (Au) to cover copper metal traces, the overlay preventing oxidation on 1:3 PZT composite with material. Also included is the formation of immersion Au nickel electrodes on the 1-3 PZT composite to achieve pad metallization for external connections.Type: ApplicationFiled: November 4, 2011Publication date: November 8, 2012Applicant: Sonavation, Inc.Inventors: Louis Regniere, Yakub Aliyu, Rainer M.

Publication number: 20100239751Abstract: Provided is a method for manufacturing multiple devices on a single piezoelectric composite substrate. The piezoelectric composite substrate is significantly larger than a size required for a single device, thus multiple sensors can be simultaneously fabricated from the same piezoelectric composite substrate.Type: ApplicationFiled: March 22, 2010Publication date: September 23, 2010Applicant: Sonavation, Inc.Inventor: Louis Regniere

Patent number: 7170958Abstract: A method and apparatus are described for adaptively removing interference from a signal. A received signal is amplified linearly along a first signal path to provide a first signal and amplified nonlinearly along a second signal path to provide a second signal. The received signal propagates through the first and second signal paths at substantially the same time. The first and second amplified signals are mixed in proportion according to determined first and second weights, respectively, to provide an output signal having interference removed. The output signal is filtered to produce a first filtered signal corresponding to a ripple envelope of the output signal and filtered substantially simultaneously to produce a second filtered signal corresponding to an average peak detected value of the output signal. The first and second filtered signals are compared to produce an error signal. The first and second weights are determined according to the error signal.Type: GrantFiled: March 12, 2003Date of Patent: January 30, 2007Assignee: Renesas Technology America, Inc.Inventors: Raymond Rizzo, Louis Regniere
