A mechanism for configuring an inspection component in a real-time model is disclosed. The inspection component includes user-configurable parameters that control the acquisition of data for the real-time model. The data acquisition and logging logic is set up using graphical blocks that are part of the larger real-time application model. When code generation is done for the model, the data acquisition logic is also automatically generated, and runs as part of the execution of a real-time task.

Code generation for data acquisition and/or logging in a modeling environment

A system and method for converting analog signals to digital signals minimize the latency of the analog to digital conversion for real-time systems. The conversion system and method implements the hardware of an analog to digital converter input/output (I/O) board and a software-based I/O-driver in an expansion bus. The hardware of the ADC I/O board executes free-running conversion of an analog signal into digital form and stores the converted values in a first level of a buffer having two levels. Previously stored converted values are pushed to the second level of the buffer when a new value is written to the first level. The I/O driver then retrieves stored values from the second level of the buffer when needed by the real-time system and gates the buffer to prevent pushing during retrieval of values from the second level.
