Disclosed is a data sequence conversion circuit for converting a plurality of input data sequences having different data widths into output data sequences having a prescribed data width without converting the input data sequences into serial data. The data sequence conversion circuit, which takes as an input any one of a plurality of input data sequences having different data widths and converts the input data sequence into an output data sequence having a prescribed data width for output, includes: a first parallel shift register for holding the input data sequence; a switch matrix for taking the data held in the first parallel shift register as input data, and for outputting the input data in distributing fashion in accordance with a rule selected by a control signal from a plurality of predetermined rules; and a second parallel shift register for taking the data output from the switch matrix as input data, and for outputting the input data as a data sequence having the prescribed data width.
