    摘要： In a microprogram controller by pipeline control which includes a memory for storing a microprogram and a program counter for representing the address of the memory, a microprogram controller includes means for judging whether or not a branch condition of a branch microinstruction is satisfied and means for converting the microinstruction fetched from the memory to a NOP (No Operation) microinstruction from the output of the next step of the memory till the outputs after a plurality of steps by the affirmation output of the judging means. When the affirmation output is obtained from the judging means, part of the memory output is loaded into the program counter and when the negation output is obtained, a value as the sum of a current value plus 1 is loaded into the program counter.

    摘要： In an apparatus for decoding cyclic codes generated by a generator polynomial ##EQU1## (where P.sub.i (x) is a m.sub.i -order irreducible polynomial) including 0-th to l-th feedback shift registers corresponding to the terms (x.sup.c +1) and P.sub.i (x), a coincidence circuit for detecting coincidence of a predetermined number of low order bits of said 0-th to l-th feedback shift registers and all-zero conditions of a high order bits, the predetermined number being a minimum one of numbers of bits (c, m.sub.1, m.sub.2, . . . m.sub.l) of the feedback shift register, the 0-th feedback shift register having an output terminal thereof connected to an input terminal thereof, and the 1st to l-th feedback shift registers each having an output terminal thereof connected to an input terminal thereof and having exclusive OR gates inserted between stages determined by the associated simple polynomial, exclusive OR gates each receiving the output of the associated feedback shift register as one input thereto; a method for decoding the cyclic code for correcting a burst error by shifting the 0-th to l-th feedback shift registers until the coincidence circuit detects the coincidence, comprising the steps of; shifting at least one of said 0-th to l-th feedback shift registers a predetermined number of times; and simultaneously shifting the 0-th to l-th feedback shift registers after the predetermined number of shifting until the coincidence circuit detects the coincidence.

    摘要： A data buffer is connected to the first and second processor and the first processor sends a start signal to the second processor, which responds to the start signal by reading data from a data source, such as an input/output device, and then writes the read out data into the data buffer. After conclusion of the writing operation, the second processor sends an end signal to the first processor which is admitted to start sending data stored in the buffer to a host processor after receipt of the start signal. The start signal and the end signal are provided to the second processor and the first processor respectively, after passing through a synchronizing circuit.

    摘要： A base station (5) comprises a base transmitter (6) for transmitting information optically to a plurality of portable stations (1 to 4) at such a predetermined time interval as is designated by portable station designating information. Each of the portable stations (1 to 4) comprises a potable transmitter (7) for transmitting information optically to the base station (5) in response to the transmission, which is designated by the portable station designating information coming from said base station (5), and within the range of the aforementioned time interval immediately after said transmission. Transmissions (ACK1 to ACK4) from the mating portable stations to the base station are individually inserted between the interval periods of the transmissions (REQ1 to REQ4) from the base station (5) to the portable stations (1 to 4) so that the single base station performs optical communications with the plurality of portable stations in a half-duplex time sharing manner.
