Patent number: 9483092Abstract: An integrated circuit includes a multiple number of processor cores and a system management unit. The multiple number of processor cores each operate at one of a multiple number of performance states. The system management unit is coupled to the multiple number of processor cores, for setting performance states of the multiple number of processor cores. The system management unit boosts a first performance state of a first processor core of the multiple number of processor cores based on both a first temperature calculated from an estimated power consumption, and a second temperature based on a temperature measurement.Type: GrantFiled: October 14, 2013Date of Patent: November 1, 2016Assignee: Advanced Micro Devices, Inc.Inventors: Samuel Naffziger, Baomin Liu, Maxat Touzelbaev

Patent number: 9263944Abstract: A valley-fill circuit with active conduction angle control allows use of a single storage capacitor instead of two. The capacitor is charged to the maximum voltage of the AC cycle, which makes possible use of low-capacitance high-voltage low ESR capacitors, increases energy storage density and decreases circuit footprint. This makes it feasible to use ceramic capacitors, such as a multilayer ceramic (MLCC), polyethylene, polypropylene, or any suitable capacitor type in addition to electrolytic capacitors. This improves the operational longevity and reduces the footprint of the circuitry.Type: GrantFiled: January 6, 2015Date of Patent: February 16, 2016Inventor: Maxat Touzelbaev

Patent number: 8635044Abstract: Embodiments of systems and methods for improved measurement of transient thermal responses in electronic systems are described herein. Embodiments of the disclosure use the known thermal transfer function of an electronic system to generate an equivalent resistor-capacitor (RC) network having a dynamic response that is identical to a given power excitation as the actual electronic system would have to that power excitation. Using the analogy between thermal and electrical systems, a Foster RC network is constructed, comprising a plurality of RC stages in which resistors and capacitors are connected in parallel. Subsequently, the analog thermal RC network is converted into an infinite impulse response (IIR) digital filter, whose coefficients can be obtained the Z-transform of the analog thermal RC network. This IIR digital filter establishes the recursive relationship between temperature output at the current time step and measured power input at the previous time step.Type: GrantFiled: April 27, 2011Date of Patent: January 21, 2014Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Maxat Touzelbaev, Yizhang Yang, Gamal Refai-Ahmed
