    • A method and an apparatus for averaging includes generating a carry using a least significant bit of each of two binary numbers, wherein the two binary numbers include a first binary number and a second binary number, and adding a first shifted binary number, a second shifted binary number, and the carry generated, thereby outputting an average of the two binary numbers. The carry generated is added to the least significant bit position. The first shifted binary number is obtained by right-shifting the first binary number by one bit, and the second shifted binary number by right-shifting the second binary number by one bit.
    • 用于平均的方法和装置包括使用两个二进制数中的每一个的最低有效位来产生进位,其中两个二进制数包括第一二进制数和第二二进制数,并且将第一移位二进制数,第二移位 二进制数和进位生成,从而输出两个二进制数的平均值。 生成的进位被加到最低有效位位置。 第一个移位的二进制数是通过将第一个二进制数字右移1位而第二个移位的二进制数通过将第二个二进制数右移一位来获得的。

    • On a stator core, there are wound T-connection primary generating windings such that the second and third single-phase windings are respectively arranged at positions electrically orthogonal to the first single-phase winding. The winding number of the first single-phase winding is 31/2 times that of the second single-phase winding or the third single-phase winding. The stator excitation windings are also wound on the stator core, which are connected to the center taps of the primary generating windings through a control rectifier. A plurality of field windings are wound on a rotor core. The field windings are arranged at positions where they are magnetically coupled with both the odd-order spatial higher harmonic components of armature reaction magnetic fields produced by currents flowing in the primary generating windings and the static magnetic fields produced by current flowing in the stator excitation windings. Due to the T-connection primary generating windings, the generator is capable of simultaneously generating not only the three-phase outputs but also the single-phase three-line outputs.

    • An arithmetic processing method and arithmetic processing device each which can reduce the number of logical stages needed to obtain the final arithmetic result, thus executing an arithmetic process such as a floating-point multiplication at high speed to reduce the arithmetic process time. According to the arithmetic processing method and arithmetic processing device, the possibility that an arithmetic exception occurs in the arithmetic result obtained through an arithmetic process is judged in the middle of the arithmetic process of the dedicated arithmetic processing unit. Transmitting an arithmetic end signal to the instruction control unit is inhibited when it is judged that there is a possibility; the arithmetic process with the possibility is executed by means of another arithmetic unit different from the dedicated arithmetic unit. Thereafter the arithmetic end signal regarding the arithmetic process is transmitted to the instruction control unit. The arithmetic processing method and arithmetic processing device can be applied to the case where an arithmetic process such as a floating-point arithmetic operation is performed in a pipeline mode.
