摘要

A code error correcting circuit interleaves original data comprising a sequence of bit data having a length of p bits by arranging the bit data of the original data into a hypothetical matrix of I rows and J columns and then selecting the bit data positioned on the i^th row along an order of the j^th column. The circuit is provided with a memory unit having a plurality of memory areas each having a length of 2ⁿ bits; and a controller for storing the original data to be interleaved into the memory areas respectively. The bit data, which are indicated by a bit select data, stored in the memory unit are sequentially outputted along an order of the i^th row and the j^th column in the hypothetical matrix as the interleaved original data.
