Abstract: The binary addition has stages with two data inputs (A,B) and a carry (CARRY IN). Sum(SUM and carry (CARRY OUT) are generated together with an intermediate signals (P= A EXOR B and G=A AND B) are provided. A switch (120) provides output selection if P is high and closes if G is high using switching stages (134,136).

Abstract: A frequency regulating circuit for the current-consumption-dependent clock supply of a circuit configuration includes a current measuring device for measuring the instantaneous current consumption of the circuit configuration, a controllable clock supply circuit, which can be connected to a clock input of the circuit configuration, and a control device for driving the clock supply circuit based upon the measured current consumption, an increase in the current consumption of the circuit configuration effecting a reduction in the clock frequency at the output of the clock supply circuit. Such a circuit ensures that a maximum permissible current consumption is not exceeded, but, at the same time, makes possible a maximum power of the circuit by a maximum clock frequency.

Abstract: The invention relates to a frequency control circuit for supplying clock-pulses, depending on the current consumption, to a circuit arrangement. Said frequency control circuit comprises a current measuring device (2) for measuring the instantaneous current consumption of the circuit arrangement (1), a controllable clock-pulse supply circuit (4) which can be connected to a clock-pulse input of the circuit arrangement (1), and a control device (3) for controlling the clock-pulse supply circuit (4) on the basis of the measured current consumption. An increase in the current consumption of the circuit arrangement causes a reduction in the clock-pulse frequency at the output (6) of the clock-pulse supply circuit (4). Said circuit ensures that a maximum acceptable current consumption is not exceeded, at the same time enabling maximum power of the circuit due to a maximum clock-pulse frequency.
