4.4 Operating System Processing Times
The run times of the operating system are based upon the following:
8 MHz P16 processor with sub--module MS3.
The processing time is reduced by approximately half for the 16 MHz processors.
A further acceleration of approximately 10 to 20% may be expected when utilizing the MS31, MS4 or MS45 sub-modules.
The signals, fed via the L and/or C bus, represent an approximate constant system loading since the bus clock runs
at 8 MHz.
