Abstract: A system and method for efficiently handling speculative execution. A load store unit (LSU) of a processor stores a commit candidate pointer, which points to a given store instruction buffered in the store queue. The given store instruction is an oldest store instruction not currently permitted to commit to the data cache. The LSU receives a first pointer from the mapping unit, which points to an oldest instruction of non-dispatched branches and unresolved system instructions. The LSU receives a second pointer from the execution unit, which points to an oldest unresolved, issued branch instruction. When the LSU determines the commit candidate pointer is older than each of the first pointer and the second pointer, the commit candidate pointer is updated to point to an oldest store instruction younger than the given store instruction stored in the store queue. The given store instruction is permitted to commit to the data cache.

Abstract: In accordance with some embodiments, a method is performed at an electronic device with a display, radio frequency (RF) circuitry, and one or more input devices. The device displays a first user interface on the display. While displaying the first user interface, the device detects a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the device determines whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the device displays a pairing affordance that initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the device displays information concerning coupling of the first peripheral and the second peripheral.

Abstract: This disclosure relates to performing cellular communication in unlicensed spectrum in a manner that accounts for the possible existence of hidden nodes by opportunistically introducing the use of RTS and CTS messages. A listen-before-talk procedure may be performed to determine whether a wireless medium is available. When the listen-before-talk procedure is complete, an amount of time until a next possible start time for communicating in the cellular communication system according to a timing synchronization scheme for the cellular communication system may be determined. The wireless medium may be occupied until the next possible start time for communicating in the cellular communication system in a manner selected based at least in part on the amount of time until the next possible start time for communicating in the cellular communication system. Cellular communication may be performed on the wireless medium at the next possible start time for communicating in the cellular communication system.

Abstract: Methods for establishing a direct peer-to-peer (“P2P”) connection between two computers are disclosed. In particular, the methods are designed to work in cases where one or both of the computers are connected to a private network, such private networks being interconnected via a public network, such as the Internet. The connections between the private network and the public network are facilitated by network address translation (“NAT”).

Abstract: A Resource Dependency Viewer for graphics processing unit (GPU) execution information is disclosed. The Resource Dependency Viewer provides profiling/debugging information concurrently with information about execution flow, resource utilization, execution statistics, and orphaned resources, among other things. A user-interactive graph (“dependency graph”) may be provided via a graphical user interface to allow interactive analysis of code executed on a GPU (e.g., graphics or compute code). Resource utilization and execution flow of encoders may be identified by analyzing contents of a GPU workload representative of a GPU execution trace to generate the dependency graph. Information about dependencies and execution statistics may be further analyzed using heuristics to identify potential problem areas. The dependency graph may include visual indicators of these problem areas.

Components such as an antenna, dock connector, microphone, and speaker may be attached to the acoustic module.

Abstract: Disclosed herein are structures, devices, and systems for detecting touch and force inputs at multiple sensing locations on a surface of an electronic device using waveguide-based interferometry. A laser light source, such as a VCSEL, inserts light into a waveguide positioned adjacent to the sensing locations, and an input at a sensing location alters the inserted light in the waveguide allowing for determination of the input's touch or force at the sensing location. Wavelength modulation of the inserted light allows isolation in frequency of the signals from each sensing location. Optical phase locking can be used to lock an absolute distance beat frequency corresponding to a stationary reference point in the waveguide.

Abstract: An electronic device in communication with a haptic feedback device that includes a touch-sensitive surface sends instructions to the haptic display to display a document with multiple characters. A respective character is displayed at a respective character size. While the haptic display is displaying the document, the device receives an input that corresponds to a finger contact at a first location on the haptic display. In response to receiving the input, the device associates a first cursor position with the first location, determines a first character in the plurality of characters adjacent to the first cursor position, and sends instructions to the haptic display to output a Braille character, at the first location, that corresponds to the first character. A respective Braille character is output on the haptic display at a respective Braille character size that is larger than the corresponding displayed character size.

Abstract: A controller and an accessory controllable by the controller can communicate using secure read and write procedures. The procedures can include encrypting identifiers of accessory characteristics targeted by a read or write operation as well as any data being read or written. The procedures can also include the accessory returning a cryptographically signed response verifying receipt and execution of the read or write instruction. In some instances, a write procedure can be implemented as a timed write in which a first instruction containing the write data is sent separately from a second instruction to execute the write operation; the accessory can disregard the write data if the second instruction is not received within a timeout period after receiving the first instruction.
