Abstract: 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.

Abstract: A system may include a data acquisition hardware device (DAQ) for acquiring sample data and/or generating control signals, and a host system with memory that may store data samples and information associated with the DAQ and host system operations. The DAQ may push hardware status information to host memory, triggered by predetermined events taking place in the DAQ, e.g. timing events or interrupts. The DAQ may update dedicated buffers in host memory with status data for any of these events. The pushed status information may be read in a manner that allows detection of race conditions, and may be used to handle data acquisition, output control signaling, and interrupts as required without the host system having to query the DAQ. The DAQ may also detect data timing errors and report those data timing errors back to the host system, and also provide improved output operations using counters.

Abstract: 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. Peripheral data buffers (PDBs) in the NIP may hold data received from and/or distributed to peer peripherals by the NIP, and network data buffers (NDBs) may hold payload data of scheduled data streams transmitted to and/or received from the network by the NIP. A data handler in the NIP may generate the payload data from the data in the PDBs, and store the payload data in the NDBs according to scheduled data handler transmit events. The data handler may obtain the data from the payload data in the NDBs and store the obtained data in the PDBs according to scheduled data handler receive events.

Abstract: A digitizer system (DS) may include one or more input channels to receive sample data, and an acquisition state machine (ASM) to organize the sample data into one or more acquisition records according to events of interest, and generate framing information corresponding to the one or more acquisition records. The events of interest may be identified by a trigger circuit in the DS, and relayed to the ASM for organizing the sample data. The DS may further include a data interface capable of receiving the one or more acquisition records and the framing information, encoding the one or more acquisition records and the framing information into encoded data, and transmitting the encoded data to an expansion module. The expansion module may receive the encoded data, decode the encoded data, and recover the sample data from the decoded data according to the framing information and the one or more acquisition records.

Abstract: An analog-to-digital-converter (ADC) timing engine may simplify the use of Delta-Sigma ADCs by compensating for the group-delay of the ADC. The compensation may render the group-delay corresponding to the ADC largely transparent to the end-user of the ADC. Therefore, multiple ADCs may be easily synchronized with each other, even if they have different group-delays, and they may further be synchronized with other types of ADCs that do not have group-delays. The data from the ADCs may also be synchronized with external events. The ADC timing engine (ATE) may be programmed with a number of parameters to set proper delays taking into account not only the group-delays corresponding to the various ADC, but delays stemming from a variety of other sources. Multiple ATEs may be synchronized with each other to ensure that data acquisition by the participating ADCs is started and/or stopped at the same point in time.

Abstract: One or more counter units of a data acquisition device used to perform sampling operations. Each of the counter units is configurable to operate in a selected one of a plurality of modes. During operation, at least one of the counter units may receive a measurement signal (or input signal) acquired by the data acquisition device and also a sample clock signal. The counter unit may sample the measurement signal based on the selected operational mode and timing of the sample clock, and at a rate that is independent of the frequency of the measurement signal. Furthermore, the counter unit may sample the measurement signal based on a selected one of a plurality of timing modes associated with the sample clock signal. The counter units may take samples of the measurement signal to perform at least one of the following types of measurements: period, frequency, pulse-width, semi-period, time separation, or event counting.

The second counter may be coupled to the first counter and to the second set of registers, and may receive the counter input signals, generate the internal control signal, and generate a second count output and a second terminal count output according to one of the respective sets of the second control data and the counter input signals.
