摘要：
We present a novel implementation for 2K/8K dual-mode small-area FFT for the OFDM de-modulator of DVB-T receivers. Besides pipelining the FFT to reduce the area and enhance the data throughput, SDF butterfly units for radix-2 and radix-4 processing are adopted to resolve the power consumption difficulty and the P&R (place and route) problem. The SRAM is used in the butterfly units to relax the auto-refreshing requirement if DRAM is used.
