Applications:

16 digital TTL I/O. The Local DSP can be used to simply move data to and from the CPCI bus or provide control for factory automation, automatic test equipment, and control systems where control feedback is necessary (PID control, etc.). Custom application software can be downloaded to the DSP via the CompactPCI bus.
