INTERLEAVE ADDRESS GENERATOR

摘要

Memory address generation apparatus 12 generates memory addresses, multiplier 15 reads from memory 14 storing row transposition patterns of a matrix a row transposition pattern value corresponding to the row number output from row counter 11 and calculates an address offset value by multiplying the transposition pattern value of the read row by the number of columns of the matrix, adder 16 reads from memory 13 storing row transposition patterns of the matrix a column transposition pattern value corresponding to the memory address generated by the memory address generation apparatus and generates an interleave address by adding up the transposition pattern value of the read column and the address offset value. <IMAGE>
