ABSTRACT:
A memory address generator in a convolutional interleaver/deinterleaver for correcting errors occurred in a data transmission of communication systems. The memory address generator includes: a first counter for counting a first variable (y) representing a location of one of total rows in a memory of the convolutional interleaver/deinterleaver, in response to a clock signal; a second counter for counting a second variable (z) representing a location of one of total columns in the memory of the convolutional interleaver/deinterleaver; a third counter for counting a third variable (x) representing a location of the memory address in an unit memory cell having a plurality of a memory address; an offset value generator for generating an offset value of the first variable in response to the first variable; a first adder for adding the second variable outputted from the second counter to the third variable outputted from the third counter; and a second adder for adding the added value from the first adder to the offset value of the first variable outputted from the offset value generator and outputting the memory address of the convolutinal interleaver/deinterleaver.
