Two instruction execution units execute different types of instructions. Two instruction selection circuits are provided. Two instruction buses are coupled to an instruction standby unit having predecoders and an instruction queue. The instruction standby unit is connected by two wait instruction buses to the input sides of the instruction selection circuits. An instruction fetch control circuit detects an instruction that has not been executed by any of the instruction execution units. Such an unexecuted instruction waits in the instruction queue, thereafter being applied, together with its predecode result, to each instruction selection circuit to be selected at the next selection time. As a result of such arrangement, fast execution of different types of instructions in parallel is accomplished.

In an adder circuit, a block carry generation logic over three consecutive digits is produced from the following equations. G0=g2+p2·g1+p2·p1·g0 /g0=/p2+/g2·/p1+/g2·/g1·/g0 In other words, the block carry generation logic /G0 is produced by a single PMOS transistor, a series circuit formed of two PMOS transistors connected in series, and a series circuit formed of three PMOS transistors connected in series. The block carry generation logic G0 is produced by a single NMOS transistor, a series circuit formed of two NMOS transistors connected in series, and a series circuit formed of three NMOS transistors connected in series. Block carry generation logics can be formed in such a way as to achieve not only a reduction of the layout area but also a higher operation rate.

Two flip-flops and decode circuits are provided. Whereas the one flip-flop receives 1-bit bit-shift-amount data B(1), the other flip-flop receives 1-bit bit-shift-amount data B(0). The decode circuits decode the bit-shift-amount data from the flip-flops. The flip-flops and the decode circuits are laterally laid out in a line. The flip-flops and the decode circuits are symmetrically laid out in bits, together with four flip-flops that receive respective 1-bit data to be bit-shifted (data A(3) to A(0)) and a bit shifter that bit-shifts the data A(3) to A(0) for a bit shift amount from said decode circuits, to form a bit slice structure and to be arranged within a data path. Accordingly, it is possible to achieve an effective reduction of the length of signal wiring over which bit-shift-amount data propagate. The reduction of wire load can be accomplished. The speed-up of data bit shift processing can be realized.

A drive apparatus for opening and closing a window glass provided in a door having an inner panel is disclosed. The drive apparatus includes a motor provided in the door and a regulator that receives drive force from the motor and selectively open and close the window glass. The door noise includes motor operating noise and vibration transmission noise that is generated when vibration of the motor is transmitted to the inner panel via the regulator. The motor is configured such that a first-order frequency component in vibration of the motor is greater than any other nth component (n is an integer greater than or equal to two), so that the first-order frequency component in the door noise is greater than any other nth frequency component (n is an integer greater than or equal to two).
