Also to provide a data processing apparatus equipped with a means to opt to apply, or not to apply, control to read instructions, that have to be executed reiteratively in loop processing, out of a small scale buffer reiteratively.

A data processing apparatus equipped with a control means to reduce the power required for memory accessing, in spite of the unavailability of a repeat instruction, by reading instructions reiteratively from a small scale buffer in loop processing can be provided. Also a data processing apparatus equipped with a means to opt to apply, or not to apply, control to read instructions, that have to be executed reiteratively in loop processing, out of a small scale buffer reiteratively can be provided.

    摘要： A data processor apparatus having first and second instruction storages for holding a series of instructions to be executed reiteratively. The number of instructions is calculated based on the difference between a start address and an end address respectively stored in a start address register and an end address register. When the number of instructions constituting the series of instructions is less than the capacity of the second instruction storage, the series of instructions is read from the second instruction storage and executed. When the number of instructions is greater than the capacity of the second instruction storage, the series of instructions is read from the first instruction storage.

    摘要： A voltage generating circuit, in which the influence of offset of an amplifier on an output voltage is reduced, has first and second bipolar transistors (Q1, Q2) having emitter terminals at the same electric potential. A base terminal of Q1 is disposed on a collector side of Q2. A first resistance element connects the collector side of Q2 with the base side of Q2; and a second resistance element (R1) connects a collector side of Q1 to R2. A third resistance element (R3) connects a base terminal of Q2 with the electric potential of the emitter terminals. An amplifier (A1) outputs a voltage based on a voltage difference between the collector sides of Q1 and Q2; and a voltage-current converting section (MP1, MP2) converts amplifier output into a current supplied to the connection node of R1 and R2. A voltage is then output on the basis of the generated current.

    摘要： Occurrence of power supply noise arising in connection with a step-down action at the time of turning on power supply is to be restrained. A step-down unit is provided with a switched capacitor type step-down circuit and a series regulator type step-down circuit, and stepped-down voltage output terminals of the step-down circuits are connected in common. The common connection of the stepped-down voltage output terminals of both step-down circuits makes possible parallel driving of both, selective driving of either or consecutive driving of the two. In the consecutive driving, even if the switched capacitor type step-down circuit is driven after driving the series regulator type step-down circuit first to supply a stepped-down voltage to loads, the switched capacitor type step-down circuit will need only to be compensated for a discharge due to the loads, and a peak of a charge current for capacitors can be kept low. When operation of the switched capacitor type step-down circuit is started, no large rush current arises, and occurrence of noise is restrained.

    摘要： An integrated circuit formed on a semiconductor chip includes voltage regulators for stepping down an externally-supplied power voltage to produce an internal power voltage, and internal circuits which operate based on the internal power voltage. The voltage regulators are laid in the area of the buffers and protective elements for the input/output signals and power voltages so that the overhead area due to the on-chip provision of the voltage regulators is minimized. The internal power voltage is distributed to the internal circuits through a looped main power line, with an electrode pad for connecting an external capacitor for stabilizing the internal power voltage being provided on it, so that the internal power voltage is stabilized and the power consumption of the integrated circuit is minimized.

    摘要： A semiconductor integrated circuit device with reduced consumption current is provided. A first step-down circuit stationarily forms internal voltage lower than supply voltage supplied through an external terminal. A second step-down circuit is switched between first mode and second mode according to control signals. In first mode, the internal voltage is formed from the supply voltage supplied through the external terminal and is outputted through a second output terminal. In second mode, operating current for a control system that forms the internal voltage is interrupted and an output high impedance state is established. The first output terminal of the first step-down circuit and the second output terminal of the second step-down circuit are connected in common, and the internal voltage is supplied to internal circuits.

    摘要： A difference between both emitter voltages of a first transistor having an emitter through which a first current flows, and at least one second transistor having an emitter through which such a second current as to reach a current density thereof smaller than that of the emitter of the first transistor flows, is applied across a first resistor. A second resistor is provided between the emitter of the second transistor and a circuit's ground potential. A third resistor and a fourth resistor are respectively provided between collectors of the first and second transistors and a power supply voltage. Such an output voltage that a collector voltage of the first transistor and a collector voltage of the second transistor become equal is formed in response to the collector voltage of the first transistor and the collector voltage of the second transistor and supplied to bases of the first and second transistors in common. A temperature sense voltage is formed from a connecting point of the first and second resistors.
