ABSTRACT:
The current consumption of a microprocessor is decreased by a switch which connects it to the electrical supply only when a control signal is received which indicates that the microprocessor is to execute a program. Specifically, an electronic switch such as a transistor is switched to the nonconductive state unless a control signal is received. For programs whose execution time is greater than the duration of the control signal, the microprocessor supplies a signal to the switch keeping it in the conductive state until the program has been fully executed.
