BLOCK INTERLEAVE DEVICE, BLOCK DEINTERLEAVE DEVICE, BLOCK INTERLEAVE METHOD, AND BLOCK DEINTERLEAVE METHOD

摘要

In a block interleaving apparatus, a block deinterleaving apparatus, a block interleaving method, and a block deinterleaving method for performing block interleaving and block deinterleaving by using a single plane of a storage unit having a storage area of one block, in order to realized further reductions in circuit scale and power consumption, a comparison reference value of a comparator 123 included in an address generation unit 103 for generating addresses of a storage unit 104 is set at a minimum value which appears in the output of a multiplier 111 and is larger than LxM-1, thereby reducing the scale of the comparator. <IMAGE>
