PURPOSE: A DFT apparatus is provided to efficiently perform DTF operation by operating radix operators in a pipeline structure. CONSTITUTION: An internal memory block(10) is partitioned into blocks and stores input data and an operation result. A write address generating unit(20) generates an address for reading out data in the internal memory block. A write address generating unit(40) generates an address for writing data in the internal memory block. An operation unit(30) applies radix operators and a twiddle factor and performs a DFT(Discrete Fourier Transform) operation.
