Abstract
An ADSL modem apparatus including an IFFT unit that performs an inverse fast Fourier transform on transmission data, an FFT unit that performs a fast Fourier transform on reception data, and a processor that performs an initialization sequence according to a protocol, is provided. During the initialization sequence, the processor maintains and enables an interleave memory to be employed. After data transmission is initiated, the processor instructs a switch controller so that an interleave unit and de-interleave unit can use the interleave memory.
