Abstract: A transmitter of a data transmission system using n transmission lanes generates an error code such as an error detection code or an error correction code from transmitted data on x transmission lanes input to an error detection/correction code generating unit, and transmits the same to a lane number switching controlling unit. The lane number switching controlling unit distributes the transmitted data and the error code to at least some of the n transmission lanes as data strings based on lane information indicating a normal lane, a failure lane, or a lane with a sign of a failure received from a receiver. Further, markers including the lane information indicating a normal or failure lane and information to detect a failure of the n transmission lanes are generated and inserted into data strings transmitted on the n transmission lanes, so that communications are performed with the receiver.

Abstract: Digital signals having respective pieces of frequency information different from each other are bundled, and transmitted at high speed. On receiving side, digital signals retaining the respective pieces of frequency information are recovered and separated. Transmitter apparatus divides pieces of transmission data that have the different pieces of frequency information and correspond to respective input channels into data blocks having a fixed length, as valid data, and subsequently multiplexes the data blocks corresponding to the respective input channels and outputs the multiplexed data to a transmission path. A receiver apparatus divides data string received into data flows and subsequently restores the transmission data, from the data blocks consecutive in each data flow and stores the restored data, and outputs transmission data corresponding to the respective data flows in synchronization with clocks generated for these data flows.

Abstract: The invention provides a technique to widely spread the frequency spectrum of switching noise generated by a switching action and to reduce the noise level at a particular frequency. A switching regulator (6A) includes a computing unit with computing function. First, in the computing unit, a pulse-width-modulation processing unit (PWM) (2a) performs pulse-width-modulation processing of receiving a feedback signal corresponding to the output of a detector 1 to determine an on-duty cycle of a pulse signal. Subsequently, for the signal and data obtained by the PWM (2a) to be subjected to further modulation processing for spectrum spreading, a branching processing is performed by making changing-over unit (2d) randomly select asynchronous-modulation processing unit (ASM) (2e) or pulse-position-modulation processing unit (PPM). When the PPM is selected, another branching processing is performed by making the changing-over unit (2d) select a first PPM (2f) or a second PPM (2g) depending on the on-duty cycle.
