DFT(Discrete Fourier TransforMATion)是數字信號分析與處理如圖形、語音及圖像等領域的重要變換工具,直接計算DFT的計算量與變換區間長度N的平方成正比.當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個數量級.本文的目的就是研究如何應用FPGA這種大規模可編程邏輯器件實現FFT的算法.本設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計實現過程中,利用遞歸結構以及成組浮點制運算方式,解決了蝶形計算、數據傳輸和存儲操作協調一致問題.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全部內置在FPGA芯片內部,使整個系統的數據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.本設計采用Verilog HDL硬件描述語言進行設計,由于在設計中采用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由函數(function)轉換而得的。此種函數,一般稱之為雜湊函數(Hashing function)或鍵值對應位址轉換(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.
