Abstract: A camera module may include a housing, a first optical assembly, a second optical assembly, a carrier, and an actuator. The first and second optical assemblies may be positioned within the camera module to receive light in opposite directions. The carrier may be positioned within the housing and include a first portion coupled to a first component of the first optical assembly and a second portion coupled to a second component of the second optical assembly. An actuator may be configured to simultaneously generate relative movement (i) between the first lens module and the first image sensor; and (ii) between the second lens module and the second image sensor.

Abstract: This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A plurality of transmission control indication states may be indicated for future use, e.g., using one or more separately identified lists. A subset of the indicated states may be activated. One or more states of the subset may be used for performing multi-transmission and reception point operation in a single downlink control information mode.

Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: An electronic device may include wireless circuitry having a radio-frequency amplifier. A method for calibrating the wireless circuitry is provided that includes characterizing a linear transformation between an input of the radio-frequency amplifier and an input of a feedback receiver, where the radio-frequency amplifier has an output that is coupled to the input of the feedback receiver via a filter and a radio-frequency coupler, obtaining a filter model based on the characterized linear transformation, and generating memory digital predistortion (mDPD) coefficients for a digital predistortion block coupled to the input of the radio-frequency amplifier based on the filter model. The generation of the mDPD coefficients can alternatively be based on an inverse filter model and can further include minimizing an error signal computed from a difference between a predistorted signal output from the digital predistortion block and a demodulated signal output from the feedback receiver.

Abstract: An electronic device may include wireless circuitry with a processor, a transceiver, an antenna, and a front-end module coupled between the transceiver and the antenna. The front-end module may include one or more power amplifiers for amplifying a signal for transmission through the antenna. Radio-frequency power amplifier circuitry may include an amplifier, an input transformer for coupling radio-frequency input signals to the amplifier, an active inductor load coupled to the input transformer, and a second order intermodulation generation circuit configured to generate and inject a second order intermodulation product into the input transformer. The injected second order intermodulation product can be used to cancel out unwanted third order intermodulation products generated by the amplifier, which reduces intermodulation distortion experienced by the amplifier circuitry.

Abstract: Devices, methods, and non-transitory program storage devices are disclosed herein to provide improved region of interest (ROI) tracking, image framing, and distortion correction for wide field of view (FOV) video image streams. The techniques disclosed may be configured, such that the image framing decisions made over the course of a captured wide FOV video image stream are able to be panned smoothly and seamlessly transition between framing a narrower portion of a wide angle camera's FOV to framing a wider portion of the wide angle camera's FOV (or vice versa), e.g., depending on the composition and movement of relevant subjects in the captured scene. The techniques disclosed herein may also be used to perform any distortion correction desired on the framed image portions in the output video image stream, e.g., based on the image portions' FOVs and/or the locations of the portions within the original wide FOV video image stream.

Abstract: Techniques are disclosed relating to memory page allocation for graphics processor. In some embodiments, a shader program includes a primary thread associated with ray tracing (that includes an instruction that indicates for the apparatus to launch one or more secondary threads). Memory resource allocator circuitry may receive a request to allocate a memory page in a page pool to a thread of the shader program, where the page pool includes a set of protected pages and a set of public pages. The allocator may allocate a page of the page pool to the requesting thread according to an allocation restriction, such that protected pages are allocable only to secondary threads that are launched based on a primary thread and public pages are allocable to both primary and secondary threads.

Abstract: In an embodiment, a processor includes hardware circuitry which may be used to authenticate instruction operands. The processor may execute instructions that perform operand authentication both speculatively and non-speculatively. During speculative execution of such instructions, the processor may execute authentication such that no differences in observable state of the processor, relative to authentication result, are detectable via a side channel. During speculative execution, a result of authentication may be deferred until speculative execution of the instruction, and additional instructions, may be completed. Upon resolution of a condition that indicates acceptance of the speculative execution, a speculative execution result may cause a processor exception and stalling of execution at the instruction to be performed.
