An Embedded Controller is simply a device that performs Embedded Controlles. The embedded market is a part of the overall DAQ market. The main differentiating feature of an embedded controller is that all system operation is not controlled by external PC. In fact the CPU running the system is actually built into the I/O system itself. While a typical, slaved data acquisition system is hosted by some type of general purpose Personal Computer complete with mouse, monitor and other human interface devices (HID), an Embedded Controller’s processor is usually dedicated to controlling the I/O system and often does not provide any direct human interface.
