Abstract
A clock pulse generator for a one-chip microprocessor permits the microprocessor to be operated on two different power sources by effectively using a single source of clock pulses, a clock pulse divider and gate circuits to gate a specific sequence of pulses to the microprocessor. The period of a slowest clock pulse signal after division is integrally related to the periods of the faster clock pulse signals so that the pulse signals are synchronously provided.
