Abstract
PURPOSE: To improve processing performance by selecting one of several oscillator outputs as a needed clock pulse (hereafter referred to as cp) according to the kind of a process that an information processor performs, and then by performing the process by using the selected clock pulse.
CONSTITUTION: While the execution of the internal processing of processor 2 is under way, the processor selects signal (k) for clock change-over circuit 12 by clock switching control signal (l) and indicates the inhibition of signal (j). As a result, since a signal of cpa is outputted for cpi, processor 2 performs its internal process using cpa while cpa is being selected by signal (k). Next, when processor 2 performs an input-output control process, processor 2 indicates the inhibition of signal (k) by selecting signal (j) for clock change-over circuit 12 by signal (l). As a result, a signal of cpd is outputted for cpi. Processor 2, therefore, uses cpd for the input-output control process.
