  • Patent number: 11184198
    Abstract: A receiver includes a decision circuit, a circuit to adjust an input signal of the decision circuit, a correction circuit and a control circuit. The decision circuit makes a data decision based on an input signal of the decision circuit. The circuit to adjust the input signal of the decision circuit adjusts the input signal of the decision circuit based on an input correction signal. The correction circuit combines a plurality of signals corresponding to different input correction parameters into a preliminary input correction signal. An input of the correction circuit is coupled to an output of the decision circuit. The control circuit maps the preliminary input correction signal into the input correction signal using a nonlinear code mapping.

  • Patent number: 11113074
    Abstract: Various embodiments of methods and systems for a modem-directed application processor boot flow in a portable computing device (“PCD”) are disclosed. An exemplary method includes an application processor that transitions into an idle state, such as a WFI state, for durations of time during a boot sequence that coincide with processing by a DMA engine and/or crypto engine. That is, the application processor may “sleep” while the DMA engine and/or crypto engine process workloads in response to instructions they received from the application processor.

  • Patent number: 11082010
    Abstract: Described herein are systems and methods that can adjust the performance of a transimpedance amplifier (TIA) in order to compensate for changing environmental and/or manufacturing conditions. In some embodiments, the changing environmental and/or manufacturing conditions may cause a reduction in beta of a bipolar junction transistor (BJT) in the TIA. A low beta may result in a high base current for the BJT causing the output voltage of the TIA to be formatted as an unusable signal output. To compensate for the low beta, the TIA generates an intermediate signal voltage, based on the base current and beta that is compared with the PN junction bias voltage on another BJT. Based on the comparison, the state of a digital state machine may be incremented, and a threshold base current is determined. This threshold base current may decide whether to compensate the operation of the TIA, or discard the chip.

  • Publication number: 20210064383
    Abstract: Aspects of the disclosure relate to improving device boot up time and subsystem availability time in a computing system using segment read scheduling. The segment read scheduling is a scheduling of order for loading subsystem images for a number of subsystem images from a memory during boot up or reset of the computing system and is based on a determined criticality value calculated from various parameters including subsystem image size, the priority of the subsystem. Additionally, the scheduled segment loading is performed according to numerous parallel loading schemes using multiple direct memory access engines and cryptography engines to increase the speed of loading the images and bringing them out of boot up or reset. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 10826818
    Abstract: Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.

  • Publication number: 20200292678
    Abstract: LIDAR measurement systems employing a multiple channel, GaN based illumination driver integrated circuit (IC) are described herein. In one aspect, the multiple channel, GaN based illumination driver IC selectively couples each illumination source associated with each measurement channel to a source of electrical power to generate a measurement pulse of illumination light. In one aspect, each pulse trigger signal associated with each measurement channel is received on a separate node of the IC. In another aspect, additional control signals are received on separate nodes of the IC and communicated to all of the measurement channels. In another aspect, the multiple channel, GaN based illumination driver IC includes a power regulation module that supplies regulated voltage to various elements of each measurement channel only when any pulse trigger signal is in a state that triggers the firing of an illumination pulse.

  • Publication number: 20200285545
    Abstract: First, second, and third threshold limits are configured. The first threshold limit corresponds to a data change at which a backup of a client should be triggered. The second threshold limit corresponds to a maximum time interval at which the backup should be triggered. The third threshold limit corresponds to a utilization of resources at the client above which the backup should not be triggered. An amount of data change since a last backup, an elapsed time, and level of resource utilization at the client is monitored. A determination is made that at least one of the amount of data change has reached the first threshold limit or the elapsed time has reached the second threshold limit. The backup of the client is prevented from occurring because the level of resource utilization at the client is above the third threshold limit.
