摘要： A network interface peripheral device (NIP) may include a network interface for communicating with a network, and an interconnect interface for communicating with a processor subsystem. First buffers in the NIP may hold data received from and/or distributed to peer peripherals by the NIP, and second buffers may hold payload data of scheduled data streams transmitted to and/or received from the network by the NIP. Payload data from the data in the first buffers may be stored in the second buffers and transmitted to the network according to transmit events generated based on a received schedule. Data may be received from the network according to receive events generated based on the received schedule, and distributed from the second buffers to the first buffers. A centralized system configuration entity may generate the schedule, manage configuration of the NIP, and coordinate the internal configuration of the NIP with a network configuration flow.

摘要： Techniques for assigning scenario-based tests to test assets are described. In an example, a scenario-based test operable to test a key performance indicator (KPI) of a System Under Test (SUT), a component behavior exhibited by a first component of the SUT, and a scenario characteristic are received. Based on the component behavior and the scenario characteristic, a first plurality of behavior models associated with the component behavior are identified. Based on the scenario characteristic a characteristic value is extracted from the scenario-based test. Each behavior model of the first plurality of behavior models is executed using the characteristic value to generate a first plurality of predicted behavior outcomes. Based on the first plurality of predicted behavior outcomes, a first test asset type from a plurality of test asset types is selected and the scenario-based test is transmitted to a test asset of the first test asset type.

摘要： Methods and computing devices for allocating test pods to a distributed computing system for executing a test plan on a device-under-test (DUT). Each test pod may include a test microservice including one or more test steps and an event microservice specifying function relations between the test microservice and other test microservices. The test pods are allocated to different servers to perform a distributed execution of the test plan on the DUT through one or more test interfaces.

摘要： A reflectometer may include two directional couplers in a parallel configuration, sharing the same section of a signal line or through-line. For example, two directional couplers may be disposed across from each other on opposite sides of the shared through-line. One of the directional couplers may couple, to a first port of the reflectometer, a portion of the signal power of a first signal flowing from the first end of the shared through-line to the second end of the shared through-line, and the other directional coupler may couple, to a second port of the reflectometer, a portion of the signal power of a second signal flowing from the second end of the shared through-line to the first end of the shared through-line. The reflectometer benefits from reduced size and signal loss with respect to reflectometers having a serial configuration. When used in vector network analyzer (VNA) systems, this results in higher output power and higher dynamic range of the VNA.

摘要： Systems and methods for communication between heterogenous processors via a virtual network interface implemented via programmable hardware and one or more buses. The programmable hardware may be configured with a multi-function bus such that the programmable hardware appears as both a network device and a programmable device to a host system. Additionally, the programmable hardware may be configured with a second bus to appear as a network device to an embedded system. Each system may implement network drivers to allow access to direct memory access engines configured on the programmable hardware. The configured programmable hardware and the network drivers may enable a virtual network connection between the systems to allow for information transfer via one or more network communication protocols.

摘要： A system and method for testing (e.g., rapidly and inexpensively) devices such as integrated circuits (IC) with integrated antennas configured for millimeter wave transmission and/or reception. The method may first perform a calibration operation on a reference device under test (DUT). The calibration operation may determine a set of reference DUT FF base functions and may also generate a set of calibration coefficients. After the calibration step using the reference DUT, the resulting reference DUT FF base functions and the calibration coefficients (or reconstruction matrix) may be used in determining far-field patterns of DUTs based on other field measurements, e.g., measurements taken in the near field of the DUT.

摘要： A user equipment device (UE) determines a beam coherence interval metric, which is a measure of stability of a beam pair over time based on a set of beam coherence intervals measured by the UE. The beam pair comprises a receive beam of the UE and a transmit beam of a base station transmitting to the UE. A beam coherence interval comprises a time duration within which a quality of a signal received on the UE receive beam remains within one of a plurality of signal quality bins. The UE also determines a hysteresis value based on the beam coherence interval metric and uses the hysteresis value to decide to switch from an active receive beam to a different receive beam that has a signal quality higher than the active receive beam by at least the hysteresis value. Alternatively, the base station determines and sends the UE the hysteresis value.

摘要： A UE determines a beam coherence interval metric that is a measure of stability of a beam pair over time based on a set of beam coherence intervals measured by the UE. The beam pair comprises a UE receive beam and a base station transmit beam. A beam coherence interval comprises a time duration within which a quality of a signal received on the UE receive beam remains within one of a plurality of signal quality bins. The UE reports the metric to the base station. The base station may update beam management resource and reporting configurations to the UE based on the metric. The UE may also use the metric to determine a hysteresis value useable by the UE to decide to switch from an active receive beam to a different receive beam having a higher signal quality by at least the hysteresis value.

摘要： A connector gap between a module connector mating surface and the backplane connector of a chassis may be eliminated through a mechanism that forcefully pushes (or pulls) the module towards the backplane and/or forcefully pushes (or pulls) the backplane toward the module. A spring-loaded or resilient element may be used to fasten the module in a way that effectively fills any designed-in and tolerance-induced gap in the connector interface, allowing the connector to fully seat. In addition, a gasket or other compressible member may be included at the connector mating interface. The gap in the connector interface may be reduced by introducing adjustable card cage members that are capable of being set during the assembly or manufacturing process using special alignment fixtures. The gap in the connector interface may also be reduced by introducing a higher tolerance capable manufacturing process, such as machining, to the card cage sub-assembly.
