    Abstract: A non-transitory computer-readable memory medium may store a first table comprising rows, wherein each row comprises a first data set identification (ID) field which stores a measurement data set identifier value identifying a measurement data set, and one or more fields for storing measurement data metadata associated with the identified data set. The medium may also store a second table comprising rows, wherein each row comprises a second data set identification (ID) field which stores a measurement data set identifier value present in the first data set ID field. The second table may also store a datapoints field for storing individual data set datapoints and a data set index field corresponding to an ordering of the individual data set datapoints. At least a portion of each of the fields of both the first and second tables may be stored in a columnar format in contiguous memory.

    Abstract: Systems and methods for interoperating between real time networks. Systems may include a plurality of ports and switch circuitry coupled to the plurality of ports. At least one port may be coupled to a first real time network carrying first traffic. One or more other ports may be coupled to a second real time network carrying second traffic. Switch circuitry may route packets between the first real time network and the one or more second real time networks based on a mapping. Routing information may be inserted in packets routed from the one or more second real time networks to the first real time network and routing information may be removed from the packets routed from the first real time network to the one or more second real time networks. Packets may be routed based on the mapping to distinct queues for the first and second traffic.

    Abstract: Systems and methods for interoperating between a time-sensitive (TS) network and a non-time-sensitive (NTS) network. The system may include a TS network switch and a TS network interface controller (NIC). Each may have a functional unit. A first port of the TS switch may be coupled to an NTS node of the NTS network and its functional unit may be configured to manage insertion and removal of tags associating packets received from the NTS network with the NTS network. The tagged packets may be forwarded on to the TS NIC via a second port. The functional unit of the TS NIC may be configured to queue tagged packets received from the TS network switch and queue and tag packets destined for the NTS network via the TS network switch.

    Abstract: In a real-time application, one or more computational tasks execute according to a time schedule and use input data from input devices and/or output data from output devices. One or more of the input devices or output devices may be unscheduled devices that attempt to access the peripheral bus at unscheduled times. Such unscheduled bus access can cause the time schedule to become comprised. Various methods for arbitrating access to the bus to better integrate the bus access with the time schedule followed by the application are described.

    Abstract: System and method for controlling thread execution via time monitoring circuitry in a processing element. Execution of a thread may be suspended via a thread suspend/resume logic block included in the processing element in response to a received suspend thread instruction. An indication of a wakeup time may be received to a time monitoring circuit (TMC) included in the processing element. Time may be monitored via the TMC using a clock included in the processing element, until the wakeup time obtains. The thread suspend/resume logic block included in the processing element may be invoked by the TMC in response to the wakeup time obtaining, thereby resuming execution of the thread

    Abstract: A method to dynamically analyze measurement data comprising measurement data sets as the measurement data is received and moved to a data warehouse. The program instructions may receive the measurement data and may extract first metadata from the measurement data. The program instructions may then extract and analyze measurement data points in the measurement data to determine if the measurement data points meet a first criteria and generate second metadata in response to determining that the measurement data points meet the first criteria. The program instructions may then provide the measurement data points, the first metadata and the second metadata to a data warehouse for storage. The analysis of the measurement data and creation of new metadata may be performed dynamically as the data is acquired and stored in the data warehouse.

    Abstract: Systems and methods for interoperating between networks. A first network may be configured to operate according to a first real time network protocol and each of one or more second networks may be configured to operate according to respective second real time traffic protocols. A mapping may specify data routing between a plurality of ports and the routing may maintain real time behavior between the first network and the one or more second networks. Additionally, routing information may be inserted in packets routed from the one or more second networks to the first network and removed from packets routed from the first network to the one or more second networks. The packets may be routed, based on the mapping, to distinct queues for the first network and the one or more second networks for processing by an application executing on at least one device.
