AbstractA data processing machine is provided with a microprocessor that functions in response to signals output by a clock oscillator to selectively change the data-processing speed of the microprocessor. The data processing machine contains a circuit for generating interruption signals at specific intervals by dividing the signals output by the clock oscillator, a signal-input device for inputting command signals that cause the microprocessor to change the data-processing speed, and a controller which, in response to signals from the input device, executes a stand-by process each time a specific number of interruption signals generated by the interruption signal generating circuit is received.
