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.
