ABSTRACT:
A multiple oscillator switching circuit for a digital processing system that includes a central processing unit having a first internal timing cycle and connected to a plurality of peripheral devices, each peripheral device having an independent internal timing cycle. The central processing unit is further connected to an oscillator switching circuit. The oscillator switching circuit includes several oscillators. Each oscillator has an output consisting of an independent internal frequency. A selected number of these oscillators have independent internal frequencies that correspond to the internal timing of the peripheral devices. These oscillator switching circuits are further connected to the central processing unit and to the output of each of the oscillators for providing a single oscillator output to the central processing unit in response to an output from the central processing unit. This capability allows the central processing unit to control its internal timing in order to slow the central processing unit to a timing cycle that will match the timing cycle of the peripheral devices. In addition the oscillator switching circuits provide an impedance matching between the output of the oscillators and the input to the central processing unit.
