    基于FPGA設計的相關論文資料大全 84篇用FPGA實現FFT的研究 劉朝暉  韓月秋 摘 要 目的 針對高速數字信號處理的要求,給出了用現場可編程門陣列(FPGA)實現的 快速傅里葉變換(FFT)方案.方法 算法為按時間抽取的基4算法,采用遞歸結構的塊浮點運 算方案,蝶算過程只擴展兩個符號位以適應雷達信號處理的特點,乘法器由陣列乘法器實 現.結果 采用流水方式保證系統的速度,使取數據、計算旋轉因子、復乘、DFT等操作協 調一致,在計算、通信和存儲間取得平衡,避免了瓶頸的出現.結論 實驗表明,用FPGA 實現高速數字信號處理的算法是一個可行的方案. 關鍵詞 離散傅里葉變換; 快速傅里葉變換; 塊浮點運算; 可編程門陣列 分類號 TP39; TN957.511 Implementation of FFT with FPGA Technology Liu Zhaohui  Han Yueqiu (Department of Electronics Engineering, BeiJing Institute of Technology, BeiJing 100081) Abstract Aim To propose a scheme for implementing FFT with FPGA in accor-dance with the requirement for high speed digital signal processing. Methods The structure of FPGA and requirement of system were considered in the experiment, radix-4 algorithm of DIT and recursive structure were adopted. The group float point arithmetic operation was used in the butterfly and the array multiplier was used to realize multiplication. Results The pipeline pattern was used to ensure the system speed, it made fetching data, calculating twiddle factor, complex multiplication and D
