Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for testing and characterization of computing systems implemented in vehicles. A testing system causes packet injectors in a vehicle networking system to execute a testing mode in which the packet injectors transmit synchronized sequences of data packets within the vehicle networking system. The testing system gathers, from logging mechanisms located within the vehicle networking system, diagnostic data describing data packet transmissions in the vehicle computer network during the testing mode. The diagnostic data includes data identifying data packets detected by the logging mechanisms and timestamps indicating times at which the data packets were detected by the logging mechanisms. The testing system generates, based on the diagnostic data and an expected diagnostic data, a testing report describing performance of the vehicle networking system during the testing mode.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for distributed processing in a vehicle networking system. A node in the vehicle networking system receives sets of processed sensor data from multiple nodes in the vehicle networking system. Each set of processed sensor data is generated using a first portion of a data processing algorithm on sensor data captured by different sets of sensors of the vehicle networking system. The node performs a second portion of the data processing algorithm based on the sets of processed sensor data received from multiple nodes, yielding a set of processed aggregated sensor data. The node may use the set of processed aggregated sensor data to provide a computer managed feature and/or transmit the set of processed aggregated sensor data to other nodes in the vehicle networking system.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a segmented ECF that includes multiple filter components to replicate an echo pulse response. The different filter components are used to replicate different portions of the echo pulse response. Each filter components can include filter coefficients of different sizes based on the portions of the echo pulse response that is replicated by the filter component. For example, a filter component that replicates a portion of the echo pulse response that includes a large reflection can include large filter coefficients suitable to replicate the larger reflection. In contrast, a filter component that replicates a portion of the echo pulse response that includes smaller reflections can include smaller filter coefficients that are suitable to replicate the smaller reflection. The output of each of the filter components is combined to replicate the full echo pulse response.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for configuration of time-sensitive networks. Time-sensitive networks utilize traffic shaping to provide for efficient and predictable flows of data through the network. A network configuration tool can be used to determine how data should be routed and shaped through the network towards its destination. The network configuration tool calculates the maximum burst size at an output port of a switch by analyzing groups of data flows that pass through the output port, rather than analyzing the data flows individually.

Abstract: Various embodiments described herein provide for in-service scanning and correction of stored data for achieving functional safety. For some embodiments, a data scanning and correction system periodically reads data from different portions (e.g., addresses) of a storage device (e.g., memory) implemented with ECC to detect any errors in the data. If an error is detected, the data scanning and correction system generates corrected data and rewrites the corrected data to the portion of the storage device. The data scanning and correction system may continuously cycle this process through different portions of the storage device to detect and correct errors while the storage device is in-service.

Abstract: Various embodiments described herein provide for data communications using decision feedback equalization (DFE) for electro-magnetic interference (EMI) cancellation in a received signal, such as a signal received over a data communication medium and at a receiver of a communication system. In particular, some embodiments use a DFE and a feed-forward equalizer (FFE) to equalize a signal received by a first physical layer device from a second physical layer device over a data communication medium, and to operate as a narrowband notch filter to cancel EMI from the received signal.
