ABSTRACT:
A computer of the present invention contains: a CPU; plural peripheral devices controlled by the CPU; a data transmission bus between the CPU and the peripheral devices and between the peripheral devices; and a clock signal source for supplying clock signals for CPU operation and data transmission. The clock signal source contains a PLL synthesizer, and two clock signals (one for the CPU and the other for the bus) are outputted from the PLL synthesizer to stop unnecessary signals (other than the clock signals) from being produced.
