In this paper, we designed FFT for European DTV and implemented system with Stratix EP1S25F672C6 FPGA At the implemented FFT, we used SIC architecture. SIC architecture is composed of algorithm-specific processing element, RAM memory, registers, and a central or distributed control unit. Designed FFT was acceptable either 2K or 8K point FFT processing, and is selectable guard interval such as 1/4, 1/8, 1/16, 1/32. Consequently, it was suitable for the standard of DVB-T(Digital Terrestrial Video Transmission System) specification. It resulted in 12% of total logic gate and 53% of total memory bit in Stratix device.
