Abstract
A digital computer system has internal and external devices, with the external devices connected to an associated bus. The digital computer system has a clock frequency which is different from that of the associated bus. Memory addresses from the central processor are decoded and for external devices, a frequency adjusting circuit divides the output from a clock oscillator to provide a system clock that is approximately the same frequency as that of the associated bus.
