PURPOSE: An interleaving address generator is provided to easily generate forward and reverse direction addresses by changing an initial stored value. CONSTITUTION: An interleaving address generator includes a multiplier(201) which multiples a preset coefficient and a constant and a plurality of address generation blocks(210-240) in which the outputs of the multiplier are calculated and generates an interleaving address. The plurality of address generation blocks is parallely connected to the multiplier by line. Each of the plurality of address generation blocks includes first adders(211,221,231,241) adding the outputs of first registers(212,222,232,242) to the outputs of the multiplier and a first register storing the outputs of the first adders. Each of the plurality of address generation blocks includes second adders(213,223,233,243) and second registers(214,224,234,244) storing the outputs of the second adders.
