1.4. Architecture Overview
A UNIDEX 600 Series controller installed in a PC acts as a dual processor system. The
PC’s CPU is one processor and the UNIDEX 600 card (referred to as the axis processor)
is another independent processor.
Although the axis processor is one processor, through the use of polling and interrupts, it
acts as three separate execution units, called the library servicer, the CNC engine, and the
motion controller (refer to Figure 1-2).
