There are five hardware versions of PMAC: the PMAC-PC, the PMAC-Lite, the PMAC-VME, the PMAC-STD and the Mini-PMAC. These cards differ from each other in their form factor, the nature of the bus interface, and in the availability of certain I/O ports. - Motorola's Digital Signal Processor (DSP) DSP56k is the CPU for PMAC, and it handles all the calculations for all eight axes. - The registers in PMAC's "DSPGATE" Gate-Array ICs are mapped into the memory space of PMAC's processor. Each DSPGATE contains four consecutively numbered channels; there may be up to 4 DSPGATEs in a PMAC system, for up to 16 channels. - There are two types of servo "DSPGATE" Gate-Array ICs: The PMAC(1) type that only allows the control of analog amplifiers with ±10 Volts command signals and the PMAC2 type that is also capable of digital direct PWM or stepper command signals. - Each PMAC channel provided by a PMAC(1) DSPGATE has one DAC output, one encoder input and four dedicated flag inputs: two end-of-travel limits, one home input and one amplifier fault input.
