INTERLEAVE APPARATUS AND INTERLEAVE METHOD

摘要

PROBLEM TO BE SOLVED: To perform interleaving with a little arithmetic throughput. SOLUTION: A data write part 101 writes input data in a storage part 102 for the unit of a row size in a row direction (in the lateral direction). The storage part 103 stores two-dimensionally arrayed data. A U/C calculation part 103 outputs the quotient and the remainder resulting from the division of the number of input data with a column size to a row size setting part 104. The row size setting part 104 outputs the size (row size) of data to be read for the unit of a column from the quotient and the remainder outputted from the U/C calculation part 103 to a data read part 105. The data read part 105 reads data of the row size outputted from the row size setting part 104 out of the storage part 102 in a column direction and outputs the data to the outside.
