Abstract: This paper verifies the front-end design of a 2-Dimensional Discrete Fourier Transform chip which is suitable for digital image processing using Nangate 45nm CMOS open cell library.Both the radix-2 decimation in time FFT algorithm and optimized pipeline structure were chose in the 2D DFT algorithm to lighten the design complexity.The functional simulation and hardware synthesis results show that the chip can work under 250MHz clock and output the DFT results of 32×32 complex matrix after 1211 clock cycles;the input and output datatype is 16-bit single precision fixed-point number.The power dissipation is only 143mW under voltage of 0.9 V.The simulation shows that the design can meet with the efficiency, precision and power dissipation requirements in low power digital image processing system.
