  • 基于FPGA的FFT數(shù)字處理器的硬件實現(xiàn)

    DFT(Discrete Fourier TransforMATion)是數(shù)字信號分析與處理如圖形、語音及圖像等領(lǐng)域的重要變換工具,直接計算DFT的計算量與變換區(qū)間長度N的平方成正比.當(dāng)N較大時,因計算量太大,直接用DFT算法進行譜分析和喜好的實時處理是不切實際的.快速傅里葉變換(Fast Fourier TransforMATion,簡稱FFT)使DFT運算效率提高1~2個數(shù)量級.本文的目的就是研究如何應(yīng)用FPGA這種大規(guī)模可編程邏輯器件實現(xiàn)FFT的算法.本設(shè)計主要采用先進的基-4DIT算法研制一個具有實用價值的FFT實時硬件處理器.在FFT實時硬件處理器的設(shè)計實現(xiàn)過程中,利用遞歸結(jié)構(gòu)以及成組浮點制運算方式,解決了蝶形計算、數(shù)據(jù)傳輸和存儲操作協(xié)調(diào)一致問題.合理地解決了位增長問題.同時,采用并行高密度乘法器和流水線(pipeline)工作方式,并將雙端口RAM、只讀ROM全部內(nèi)置在FPGA芯片內(nèi)部,使整個系統(tǒng)的數(shù)據(jù)交換和處理速度得以很大提高,實際合理地解決了資源和速度之間相互制約的問題.本設(shè)計采用Verilog HDL硬件描述語言進行設(shè)計,由于在設(shè)計中采用Xilinx公司提供的稱為Core的IP功能塊極大地提高了設(shè)計效率.

    雜湊法(Hashing)的搜尋與一般的搜尋法(searching)是不一樣的。在雜湊法中,鍵值(key value)或識別字(identifier)在記憶體的位址是經(jīng)由函數(shù)(function)轉(zhuǎn)換而得的。此種函數(shù),一般稱之為雜湊函數(shù)(Hashing function)或鍵值對應(yīng)位址轉(zhuǎn)換(key to address TransforMATion)。對於有限的儲存空間,能夠有效使用且在加入或刪除時也能快的完成,利用雜湊法是最適當(dāng)不過了。因為雜湊表搜尋在沒有碰撞(collision)及溢位(overflow)的情況下,只要一次就可擷取到。

    This is a little console mode utility program which is able to (de-)compress single files with a static Arithmetic compression algorithm. You could easily add the RLE/BWT/MFT data TransforMATion algorithms. Just rip the corresponding classes out of my HuffComp source code. I won t add these ones in the next time.
