<p>A parallel transmission method is disclosed, which comprises a submethod of transmitting portion for transmitting parallel data of a plurality of channels as encoded data of a plurality of lines and a submethod of receiving portion for decoding parallel data of a plurality of lines from encoded data of the plurality of channels, the submethod of transmitting portion comprising the steps of multiplying the frequency of a clock by a predetermined number so as to generate a multiplexing clock, separating input signals composed of parallel data of a plurality of channels and additional data for code transformation into a plurality of groups, transforming parallel data into serial data with the multiplexing clock, mutually substituting the resultant data of the plurality of channels from time to time, and generating encoded data containing the additional data of the plurality of lines, and the submethod of receiving portion comprising the steps of, synchronizing encoded data of the plurality of lines with the additional data, substituting the resultant data of the plurality of lines in the inverse order of the transmitting portion, removing the additional data from the resultant data, successively arranging the resultant data of each group, dividing the frequency of a transmission clock by a predetermined number so as to generate an original clock, and transforming serial data of each group into parallel data. Thus, with p : 1 parallel-serial transforming circuits, parallel data transmission with parallel degree of p x q - 1 can be accomplished by p times higher transmission line clock speed. <IMAGE></p> |
