A system can comprise a memory operatively coupled to a processor that executes stored executable components comprising a first controller, a second controller, and a failure indication component that provides a first notification based on a first detection of a first failure at the second controller, and a second notification based on a second detection of a second failure at the first controller. Further, the executable components can comprise a control transfer component that automatically transfers control of a second display unit from the v controller to the first controller based on the first notification, or control of a first display unit from the first controller to the second controller based on the second notification.Type: GrantFiled: June 7, 2017Date of Patent: December 3, 2019Assignee: GE Aviation Systems LLCInventor: David Allen Fairchild

Patent number: 10452581Abstract: Memory descriptor list caching and pipeline processing techniques are described. In one or more examples, a method is configured to increase efficiency of buffer usage within a pipeline of a computing device. The method includes creation of a buffer in memory of the computing device and caching of a memory descriptor list by the computing device that describes the buffer in a buffer information cache and has associated therewith a handle that acts as a lookup to the memory descriptor list. The method also includes passing the handle through the pipeline of the computing device for processing of data within the buffer by one or more stages of the pipeline such that access to the data is obtained by the one or more stages by using the handle as the lookup as part of a call to obtain the memory descriptor list for the buffer from the buffer information cache.Type: GrantFiled: October 25, 2017Date of Patent: October 22, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Mei L. Wilson, Jitesh Krishnan, Sathyanarayanan Karivaradaswamy

Patent number: 10437739Abstract: Methods, apparatus and associated techniques and mechanisms for reducing latency in accelerators. The techniques and mechanisms are implemented in platform architectures supporting shared virtual memory (SVM) and includes use of SVM-enabled accelerators, along with translation look-aside buffers (TLBs). A request descriptor defining a job to be performed by an accelerator and referencing virtual addresses (VAs) and sizes of one or more buffers is enqueued via execution of a thread on a processor core. Under one approach, the descriptor includes hints comprising physical addresses or virtual address to physical address (VA-PA) translations that are obtained from one or more TLBs associated with the core using the buffer VAs. Under another approach employing TLB snooping, the buffer VAs are used as lookups and matching TLB entries ((VA-PA) translations) are used as hints. The hints are used to speculatively pre-fetch buffer data and speculatively start processing the pre-fetched buffer data on the accelerator.Type: GrantFiled: September 26, 2017Date of Patent: October 8, 2019Assignee: Intel CorporationInventor: Vinodh Gopal

Patent number: 10424253Abstract: A display device and a power monitoring circuit. The power monitoring circuit monitors whether or not first power is ordinarily output from a power management integrated circuit (PMIC). When the first power is not ordinarily output, the power monitoring circuit outputs an error detection signal indicative of an abnormality in the PMIC to a main controller. The display device includes the power monitoring circuit. The operating state of the PMIC supplying power required for the driving of a display panel can be monitored.Type: GrantFiled: August 21, 2017Date of Patent: September 24, 2019Assignee: LG Display Co., Ltd.Inventors: Sangyong Kim, Moo Kyoung Hong

Patent number: 10387343Abstract: According to embodiments of the present invention, machines, systems, methods and computer program products for processing events including efficiently processing interrupt service requests for peripheral devices, such as hardware accelerators, utilized in parallel processing are provided. For each core engine of a peripheral device, the peripheral device detects whether one or more interrupt signals have been generated. Information associated with the one or more interrupt signals are stored in one or more registers of peripheral device memory, for each core engine. The information is aggregated and stored in a vector of registers in the peripheral device memory, and the aggregated information is written to memory associated with a CPU to enable CPU processing of interrupt requests from each core engine of the peripheral device.Type: GrantFiled: April 7, 2015Date of Patent: August 20, 2019Assignee: International Business Machines CorporationInventors: Chachi Ching, John A.

Patent number: 10347043Abstract: Improved techniques of managing graphical user interface (GUI) objects based on portal layers (or simply portals) are described. A portal refers to a logical reference to a GUI object specified by an application that enables an operating system to access and process the specified GUI object without affecting any of the rules/assumptions required by the application for the specified GUI object. Portals can assist with reducing computational resources required for rendering by assisting with reducing or eliminating the use of snapshots for rendering. One embodiment includes generating a layer tree; identifying a first sub-tree of the layer tree as portal content; establishing a portal as a reference to the portal content in a second sub-tree of the layer tree; generating a render tree based on the layer tree; rendering the render tree to create an image; and presenting the image on a display.Type: GrantFiled: June 6, 2017Date of Patent: July 9, 2019Assignee: Apple Inc.Inventors: Bartosz Ciechanowski, Chendi Zhang
