    摘要: The object of the present invention is to provide a semiconductor integrated circuit device wherein the input signal is made to have a low amplitude to shorten transition time of the input signal, said integrated circuit device operating at a low power consumption, without flowing of breakthrough current, despite entry of the input signal featuring low-amplitude operations, and said integrated circuit device comprising a gate circuit, memory and processor. When input signal is supplied through the NMOS pass transistor, said input signal is input to the gate of the first NMOS transistor, and at the same time, is input into the gate of the first PMOS transistor which performs complementary operation with said first NMOS transistor through the second NMOS transistor; said first PMOS gate is connected to the power supply potential through the second PMOS transistor, and the gate of the said second NMOS transistor is connected to the power supply potential; wherein the gate of the said second PMOS transistor gate is controlled by the signal which is connected with both the drain of the said first NMOS transistor and the drain of the said first PMOS transistor.

    摘要: An arithmetic unit which accepts two numerical values and executes an operation by the use of the two numerical values has an adder-subtracter for executing an addition or a subtraction on the basis of two numerical values obtained directly or indirectly from the accepted two numerical values; a normalizer for executing a normalizing process in which a mantissa part of an added or subtracted result is shifted so that a high-order digit having been developed anew in the result may come to a predetermined position, and in which an exponent part of the result is corrected in accordance with the number of shift places in the shift of the mantissa part; and a rounding device for executing a rounding process in which, on condition that the mantissa part of the added or subtracted result exceeds a predetermined number of digits, the number of digits of the mantissa part is reduced in conformity with a rounding mode designated beforehand. The rounding device executes at least part of the rounding process by the use of the numerical values not yet subjected to the normalizing process, in parallel with the execution of the adder-subtracter or the normalizer.
