Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. Both stored maps and tracking maps used by portable devices may have wireless fingerprints associated with them. The portable devices may maintain wireless fingerprints based on wireless scans performed repetitively, based on one or more trigger conditions, as the devices move around the physical world. The wireless information obtained from these scans may be used to create or update wireless fingerprints associated with locations in a tracking map on the devices. One or more of these wireless fingerprints may be used when a previously stored map is to be selected based on its coverage of an area in which the portable device is operating. Maintaining wireless fingerprints in this way provides a reliable and low latency mechanism for performing map-related operations.

Abstract: A Wi-Fi device includes a controller coupled to a writeable memory implementing a MAC and PHY layer and to a transceiver. Connection data stored in the writeable memory includes Wi-Fi connection parameters including ?1 router MAC level information or a most recently utilized (MRU) channel used, and IP addresses including ?1 of an IP address of the Wi-Fi device, IP address of the MRU router, an IP address of a MRU target server, and an IP address of a network connected device. An accelerated reconnecting to a Wi-Fi network algorithm is implemented by the processor is for starting from being in a network disconnected state, establishing current connection parameters for a current Wi-Fi network connection using the Wi-Fi connection parameters for at least one MAC layer parameter for the MAC layer.

Abstract: A heterogeneous multi-core system that executes a real-time system for an automobile includes a plurality of system-on chips in electronic communication with one another. Each system-on-chip includes a plurality of central processing units (CPUs) arranged into a plurality of logical domains. The heterogeneous multi-core system also includes a plurality of scheduled tasks that are executed based on an execution pipeline and each execute a specific set of tasks for one of the logical domains. The plurality of scheduled tasks includes at least one offset scheduled task that is executed at an offset time and a reference scheduled task located at an execution stage upstream in the execution pipeline relative to the offset scheduled task. The reference scheduled task communicates data to the offset scheduled task and the offset time represents a period of time measured relative to the reference scheduled task.
