摘要： A data transfer apparatus includes a transmitting unit, a transmission controlling unit, and a generating unit. The transmitting unit transmits transmit data over a transmission channel having a plurality of lines, such that the transmit data are assigned to the plurality of lines by information unit of the transmit data, the information unit. The transmission controlling unit appends control data to transfer data to be transferred to a receiving side to compose the transmit data, the control data being for controlling transmission and reception of the transfer data. The generating unit obtains information about the number of the lines. The generating unit determines, based on the number of the lines and the number of information units of the control data, the number of information units of the transfer data that makes the number of information units of the transmit data integral multiple of the number of the lines.

摘要： A data transmission apparatus includes a packet generation section, a frame encoding section, a transmission section, a reception section, a frame decoding section and a packet extraction section. The packet generation section generates a packet upon request. The frame encoding section generates a frame having a predetermined length by dividing the packet or adding dummy data to the packet and generates an error-correcting-code-added frame by adding an error correcting code to the frame. The transmission section transmits the generated error-correcting-code-added frame through a transmission line. The reception section receives the error-correcting-code-added frame. The frame decoding section performs an error detection and an error correction for the error-correcting-code-added frame. The packet extraction section extracts the packet by removing the error correcting code from the error-correcting-code-added frame for which the error detection and the error correction have been performed.

摘要： A partial response (PR) waveform generator generates a digital value sequence of an expected PR waveform based on the output of a soft-decision Viterbi detector included in, for example, a first-stage decoder unit incorporated in an iterative decoder. The generator also generates flag information indicative of whether reliability of the digital value sequence is low or high, in parallel with the generation of the digital value sequence. An error detector detects error values in a PR equalized sample value sequence, needed for feedback control of a control target, using the digital value sequence of the expected PR waveform as a digital value sequence of a reference waveform. An error output controller controls the output of the error values detected by the error detector in accordance with the state of the flag information generated by the generator.
