Patent number: 10248177Abstract: A processor system includes first and second regulators for regulating an adjusted supply voltage. The first and second regulators generate a plurality of control signals to regulate an adjusted power supply voltage and that generate a charge when a droop level falls below a droop threshold value by implementing first and second control loops. A supply adjustment block with the two regulators and control loops are provided for each processor core allowing different cores to have different regulated supply levels all based on one common supply. One regulator is a global regulator while another is a local regulator found in each of the processing tiles. Processing tiles are grouped into two groups wherein one group includes tiles that may powered down to save power. Voltage rails of the two groups are selectively connected to equalize voltage levels when both groups are powered on and operating.Type: GrantFiled: October 21, 2015Date of Patent: April 2, 2019Assignee: Advanced Micro Devices, Inc.Inventors: Miguel Rodriguez, Stephen Victor Kosonocky

Patent number: 10241931Abstract: A table walker receives, from a requesting entity, a request to translate a first address into a second address associated with a page of memory. During a corresponding table walk, when a lock indicator in an entry in a reverse map table (RMT) for the page is set to mark the entry in the RMT as locked, the table walker halts processing the request and performs a remedial action. In addition, when the request is associated with a write access of the page and an immutable indicator in the entry in the RMT is set to mark the page as immutable, the table walker halts processing the request and performs the remedial action. Otherwise, when the entry in the RMT is not locked and the page is not marked as immutable for a write access, the table walker continues processing the request.Type: GrantFiled: January 27, 2017Date of Patent: March 26, 2019Assignee: ADVANCED MICRO DEVICES, INC.Inventors: David A.

Patent number: 10235290Abstract: Systems, apparatuses, and methods for sorting memory pages in a multi-level heterogeneous memory architecture. The system may classify pages into a first “hot” category or a second “cold” category. The system may attempt to place the “hot” pages into the memory level(s) closest to the systems' processor cores. The system may track parameters associated with each page, with the parameters including number of accesses, types of accesses, power consumed per access, temperature, wearability, and/or other parameters. Based on these parameters, the system may generate a score for each page. Then, the system may compare the score of each page to a threshold. If the score of a given page is greater than the threshold, the given page may be designated as “hot”. If the score of the given page is less than the threshold, the given page may be designated as “cold”.Type: GrantFiled: June 26, 2015Date of Patent: March 19, 2019Assignee: Advanced Micro Devices, Inc.Inventors: Sergey Blagodurov, Gabriel H.

Patent number: 10235220Abstract: A system, method, and computer program product are provided for improving resource utilization of multithreaded applications. Rather than requiring threads to block while waiting for data from a channel or requiring context switching to minimize blocking, the techniques disclosed herein provide an event-driven approach to launch kernels only when needed to perform operations on channel data, and then terminate in order to free resources. These operations are handled efficiently in hardware, but are flexible enough to be implemented in all manner of programming models.Type: GrantFiled: September 7, 2012Date of Patent: March 19, 2019Assignee: Advanced Micro Devices, Inc.Inventors: Lee W.

Patent number: 10237335Abstract: Systems, apparatuses, and methods for managing cluster-level performance variability without a centralized controller are described. Each node of a multi-node cluster tracks a maximum and minimum progress across the plurality of nodes for a workload executed by the cluster. Each node also tracks its local progress on its current task. Each node also utilizes a comparison of the local progress to reported maximum and minimum progress across the cluster to identify a critical, or slow, node and whether to increase or reduce an amount of power allocated to the node. The nodes append information about the maximum and minimum progress to messages sent to other nodes to report their knowledge of maximum and minimum progress with other nodes. A node updates its local information if the node receives a message from another node with more up-to-date information about the state of progress across the cluster.Type: GrantFiled: June 15, 2016Date of Patent: March 19, 2019Assignee: Advanced Micro Devices, Inc.Inventor: Leonardo Piga

Publication number: 20190076618Abstract: Described herein are a method, system and apparatus for mitigating motion sickness in a virtual reality (VR) environment. In an implementation, the system and apparatus can include a VR controller board, a processor and a VII headset. In an implementation, the processor and VR headset are an integrated device. In general, the method includes capturing measurements using the VR controller board. The measurements are indicative of user directional movements in a physical environment relative to the VR environment. In an implementation, the measurements relate to changes in the location of the center of mass of the user relative to the VR controller board. The processor uses the measurements to determine predetermined actions in the VR environment. The predetermined actions are then executed in the VR environment nearly simultaneous with the user directional movements in the physical environment.Type: ApplicationFiled: December 13, 2017Publication date: March 14, 2019Applicant: Advanced Micro Devices, Inc.Inventor: Evgene Fainstain

Patent number: 10223124Abstract: A processor employs one or more branch predictors to issue branch predictions for each thread executing at an instruction pipeline. Based on the branch predictions, the processor determines a branch prediction confidence for each of the executing threads, whereby a lower confidence level indicates a smaller likelihood that the corresponding thread will actually take the predicted branch. Because speculative execution of an untaken branch wastes resources of the instruction pipeline, the processor prioritizes threads associated with a higher confidence level for selection at the stages of the instruction pipeline.Type: GrantFiled: January 11, 2013Date of Patent: March 5, 2019Assignee: Advanced Micro Devices, Inc.Inventors: Ramkumar Jayaseelan, Ravindra N Bhargava

Patent number: 10223162Abstract: Systems, apparatuses, and methods for tracking system resource utilization of guest virtual machines (VMs). Counters may be maintained to track resource utilization of different system resources by different guest VMs executing on the system. When a guest VM initiates execution, stored values may be loaded into the resource utilization counters. While the guest VM executes, the counters may track the resource utilization of the guest VM. When the guest VM terminates execution, the counter values may be written to a virtual machine control block (VMCB) corresponding to the guest VM. Scaling factors may be applied to the counter values to normalize the values prior to writing the values to the VMCB. A cloud computing environment may utilize the tracking mechanisms to guarantee resource utilization levels in accordance with users' service level agreements.Type: GrantFiled: April 13, 2016Date of Patent: March 5, 2019Assignee: Advanced Micro Devices, Inc.Inventors: Michael T.

Publication number: 20190066371Abstract: A technique for performing rasterization and pixel shading with decoupled resolution is provided herein. The technique involves performing rasterization as normal to generate fine rasterization data and a set of (fine) quads. The quads are accumulated into a tile buffer and coarse quads are generated from the quads in the tile buffer based on a shading rate. The shading rate determines how many pixels of the fine quads are combined to generate coarse pixels of the coarse quads. Combination of fine pixels involves generating a single coarse pixel for each such fine pixel to be combined. The positions of the coarse pixels of the coarse quads are set based on the positions of the corresponding fine pixels. The coarse quads are shaded normally and the resulting shaded coarse quads are modified based on the fine rasterization data to generate shaded fine quads.Type: ApplicationFiled: August 25, 2017Publication date: February 28, 2019Applicant: Advanced Micro Devices, Inc.Inventors: Skyler Jonathon Saleh, Christopher J. Brennan, Andrew S. Pomianowski, Ruijin Wu
