    摘要: A coding apparatus includes shift register, input register and logical operation section. The shift register performs bit shifting on an input bit sequence and stores one bit of the input bit sequence after another. The input register stores coefficients of terms on respective orders of a generator polynomial. The logical operation section obtains logical products of the respective bits stored on the shift register and associated bits stored on the input register and a logical product of each one bit input to the shift register and an associated bit stored on the input register so that the earlier a bit of the input bit sequence was input, the higher-order one of the coefficients in the terms of the polynomial the input bit is associated with. Next, the logical operation section derives an exclusive logical sum of the products and then outputs the sum as a bit of a code sequence.

    摘要: To enable high-speed CRC operation and flexible use of various generating polynomials without causing significant increase in circuit scale, the CRC operation unit uses circuits generally provided for a DSP and some additional circuits. The CRC operation unit includes: a generating polynomial supply section having a first general register for storing an arbitrary generating polynomial and a selector for selectively outputting the generating polynomial or data of which all bits has a value of 0; an operation data supply section having a memory, a shift register, a second general register, and a barrel shifter, for outputting operation data for CRC operation based on transmitting/receiving data; an operation section for performing CRC operation using the generating polynomial output from the generating polynomial supply section and the operation data output from the operation data supply section; and an operation instruction execution control section for controlling the operations of the above sections.

    摘要: An execution control instruction is applied to an information processor of the type processing instructions by pipelining to suppress the occurrence of branch hazard. The execution control instruction contains: a condition field for specifying an execution condition; and an instruction-specifying field for defining, in binary code, the number of instructions to be executed only conditionally. In response to the execution control instruction, a nullification controller decides, based on control flags provided from an arithmetic logic unit, whether or not the execution condition specified by the condition field is satisfied. And based on the outcome of this decision, the controller determines whether or not that number of instructions, which has been defined by the instruction-specifying field for instructions succeeding the execution control instruction, should be nullified. If the controller has determined that the specified number of succeeding instructions should be nullified since the execution condition is not met, then the controller asserts a nullification signal to be supplied to the arithmetic logic unit. In this manner, a large number of succeeding instructions are executable conditionally using an execution control instruction of a short word length.

    摘要: A method of operating a digital signal processor is provided. The digital signal processor may be provided as a radio communication mobile station, a radio communication base station apparatus, or a CDMA radio communication system. Each path metric PM1 and PM0 of an old state is added to each branch metric BM1 and BM0 separately. A path metric of a new state N is formed by comparing the value of PM1+BM1 to the value of PM0+BM0. A path metric of a new state N+2k−2 is formed by comparing the value of PM1+BM0 to PM0+BM1.

A first processor generates a first address for defining a location to be accessed in the first memory and a second address for defining a location to be accessed in the second memory. A second processor generates a third address. A memory control section controls access to the first memory and access to the second memory. The memory control section includes an address conversion section for converting the third address so as to represent either one of the first address and the second address.

    摘要: Excess sludge production in a bioreactor of a wastewater treatment plant in which excess sludge is being produced is reduced by adding an activated sludge material having a chitinase specific activity of at least 150 Units/g-MLSS and a pectinase specific activity of at least 120 Units/g-MLSS to the bioreactor. After the addition of the activated sludge material, the bioreactor is controlled by adding the activated sludge material when any one of the chitinase activity, the pectinase activity, and the protease specific of the sludge in the bioreactor drops below the lower limits of 50 Units/L, 40 Units/L, and 0.3 Units/L, respectively.
