Summary: We propose a single-chip 400-MFLOPS 2-D FFT processor VLSI architecture. This processor integrates 380,000 transistors in an area of 11.5811.58 mm2 using 0.8 µm CMOS technology with a typical machine cycle time of 25 ns, and executes 2n2n point 2-D FFT in real time, e.g., 256256 point FFT is executed in 14 ms. This excellent performance in terms of both speed and dynamic range makes the real-time processing practical for video as well as speech processing.
