Abstract: Embodiments are disclosed for active cancellation of noise in motion sensor signals. In some embodiments, a method comprises: obtaining a motion sensor signal from a motion sensor; obtaining a reference signal indicative of parasitic vibration from a vibration source mechanically coupled to the motion sensor; generating, using an adaptive noise canceller, an estimate of the parasitic vibration; and using the estimated parasitic vibration to cancel the parasitic vibration from the motion sensor signal.

Abstract: Various implementations disclosed herein include devices, systems, and methods that present content items (e.g., movies, TV shows, home-made videos, etc.) on electronic devices such as HMDs. Some implementations adjust what is being displayed by the electronic devices to mitigate optical module-based artifacts (e.g., ghosting). For example, in an HMD with a catadioptric lens, a mirror layer may leak some light to produce ghosting artifacts that may be mitigated by adjusting brightness, dynamic range, contrast, light-spill, color, etc. Some implementations utilize adjustments that are based on content item awareness (e.g., adjustments based on the peak brightness of the scene in a movie that is being displayed within an extended reality (XR) environment, etc.). Some implementations provide adjustments based on environment awareness (e.g., how dark is the surroundings or pass-through environment) and/or optical module modeling. The adjustments may change a particular content item and/or an environment in which it is presented.

Abstract: Some examples of the disclosure are directed to systems and methods for displaying three-dimensional models of virtual three-dimensional environments. In some examples, the three-dimensional model includes representations of the virtual object(s) included in the environment, a representation of a viewpoint of a user of the electronic device in the environment, and a representation of a viewpoint of a second user of a different electronic device in the environment. In some examples, in response to receiving an input requesting to display the virtual three-dimensional environment (e.g., at full size), the electronic device displays the virtual three-dimensional environment from the viewpoint of the user of the electronic device indicated in the model.

Abstract: Techniques are disclosed involving operand management using a fusion buffer. A processor includes operand management circuitry, where the operand management circuitry includes a fusion buffer, and execution circuitry. In one embodiment, the operand management circuitry is configured to detect a first storage instruction operation that is executable to store operand values usable by one or more consumer instruction operations and store the first storage instruction operation in the fusion buffer. In response to detecting a drop condition associated with the first storage instruction operation, the operand management circuitry is configured to remove the first storage instruction operation from the fusion buffer without forwarding the first storage instruction operation for execution. In response to detecting a buffer vacate condition and not detecting the drop condition the operand management circuitry is configured to forward the first storage instruction operation for execution by the execution circuitry.

Abstract: Techniques are disclosed relating to integrated circuits that support matrix operations. In various embodiments, an integrated circuit comprises a dot product accumulate circuit that includes a dot product circuit configured to determine a dot product of a first vector and a second vector, and an adder circuit coupled to an output of the dot product circuit and configured to add a result of the dot product and an accumulation value. The integrated circuit further includes an accumulator cache coupled to an input of the adder circuit and an output of the adder circuit. The accumulator cache is configured to provide the accumulation value to the adder circuit and store a result of the add as a subsequent accumulation value for a subsequent dot product accumulate operation.

Abstract: Techniques are disclosed relating to managing power allocation for component circuits coupled to one or more power sources. A system can include a plurality of component circuits, a plurality of power sources, and a power splitter circuit. The power splitter circuit may access, from programmable registers, a mapping between ones of the plurality of component circuits and ones of the plurality of power sources. The power splitter circuit may then allocate power to a given one of the plurality of component circuits based on one or more power budgets of one or more power sources that are mapped to the given component circuit as indicated by the mapping. In various cases, the power splitter circuit may determine that multiple power sources supply power to a particular component circuit and allocate power to the particular component circuit based on respective power budgets of the multiple power sources.

Abstract: A head-mountable device can include a display frame, an optical component disposed within the display frame, a facial interface, and a rigid bumper connected to the display frame. The rigid bumper can be positioned between the display frame and the facial interface and can further define a gap between the optical component and the facial interface. The facial interface can also include a cushion layer that can be rated for applied loads in a first force range. Furthermore, a stop can be connected to the head-mountable display, wherein the stop can be rated for applied loads within a second force range that is higher than the first force range. The facial interface can further include a front surface facing toward the head-mountable display and a rear surface that can contact a face. A set of structural posts can also be attached to the head-mountable display and positioned adjacent to a forehead region and a maxilla region of a face, wherein a portion of each structural post of the set of structural posts can be embedded in the facial interface.
