  • Publication number: 20120159936
    Abstract: An exhaust pipe through which an exhaust port of an internal combustion engine and a catalyst for purifying an exhaust gas of the internal combustion engine are connected to each other includes a porous portion that is provided on at least a part of an inner peripheral face of the exhaust pipe. A thermal conductivity that the porous portion exhibits in a high temperature state where a temperature of the exhaust gas is as high as it is required to radiate a heat of the exhaust gas through the exhaust pipe is at least ten times higher than a thermal conductivity that the porous portion exhibits in a low temperature state where the temperature of the exhaust gas is as low as it is required to warm the catalyst up.

  • Publication number: 20080282136
    Abstract: A circuit outputs, upon receipt of data and a parity of the data, count information on the number of bits in the data represented as a base-n number (n: a natural number equal to or larger than 2) and the parity of the count information. The circuit includes a determining unit and an inverting unit. The determining unit determines that the number of bits in the data represented as a base-n number is a specific value. The inverting unit outputs, as the parity of the count information, any one of a value of the parity of the data and an inverted value of the parity depending on a result of determination by the determining unit.

  • Patent number: 7437399
    Abstract: 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.

  • Publication number: 20080172551
    Abstract: To verify an addition-function of a floating-point adder-subtractor in a processor, parameters such as the number of verification patterns of a verification program are set, a floating-point addition instruction to be verified is created, and operands used for this addition are created at random. The floating-point addition instruction thus created is emulated only by a fixed-point instruction and processed only by using the fixed-point execution element, thereby creating an expectation value. The floating-point addition instruction is computed by using the floating-point adder-subtractor to be verified, and the created expectation value is compared with the operation result. If they do not correspond to each other, the set number of operation patterns is checked. If the number has reached a prescribed value, the operation verification is terminated in the normal manner.

  • Patent number: 7093110
    Abstract: In the structure of register files composed of a master register file and a working register file, when data is read, the working register file is accessed. When data is written, the both the master register file and the working register file are accessed. In the working register file, data of the current window, and data preceded thereby, and data followed thereby are stored. Thus, even if the SAVE instruction or the RESTORE instruction are successively executed, instructions can be processed out of order. As a result, the efficiency of the process is improved.

  • Patent number: 5838601
    Abstract: 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.

  • Patent number: 5694027
    Abstract: 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.
