PMAC Quick Reference Guide
12 Introduction
A faster than 20 MHz PMAC will perform calculations faster, in proportion to the corresponding clock
rate increase. In general, a clock rate increase is used to increase the real time interrupt (RTI) share of the
total computational time available. These cases include applications where large move calculations are
involved (small-moves contouring), maintaining the same servo-loop rate and therefore the same control
performance.
