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N較大時，因計算量太大，直接用DFT算法進行譜分析和信號的實時處理是不切實際的。快速傅立葉變換(Fast Fourier Transformation，簡稱FFT)使DFT運算效率提高1～2個數(shù)量級。其原因是當N較大時，對DFT進行了基4和基2分解運算。FFT算法除了必需的數(shù)據(jù)存儲器ram和旋轉因子rom外，仍需較復雜的運算和控制電路單元，即使現(xiàn)在,實現(xiàn)長點數(shù)的FFT仍然是很困難。本文提出的FFT實現(xiàn)算法是基于FPGA之上的，算法完成對一個序列的FFT計算，完全由脈沖觸發(fā)，外部只輸入一脈沖頭和輸入數(shù)據(jù)，便可以得到該脈沖頭作為起始標志的N點FFT輸出結果。由于使用了雙ram，該算法是流型(Pipelined)的，可以連續(xù)計算N點復數(shù)輸入FFT，即輸入可以是分段N點連續(xù)復數(shù)數(shù)據(jù)流。采用DIF(Decimation In Frequency)-FFT和DIT(Decimation In Time)-FFT對于算法本身來說是無關緊要的，因為兩種情況下只是存儲器的讀寫地址有所變動而已，不影響算法的結構和流程，也不會對算法復雜度有何影響。

ET++ is a portable and homogenous object-oriented class library integrating user interface building blocks, basic data structures, and high level application framework components. ET++ eases the building of highly interactive applications with consistent user interfaces following the direct manipulation principle. The ET++ class library is implemented in C++ and can be used on several operating systems and window system platforms. Since its initial conception the class library has been continuously redesigned and improved. It started with an architecture which was close to MacApp. During several iterations a new and unique architecture evolved. A byproduct of the ET++ project is a set of tools, which were designed to support the exploration of ET++ applications at run-time. 設計模式一書引用的主要參考例程，一個跨平臺的應用框架，基于C++實現(xiàn)，是學習面向對象的經(jīng)典源碼.
