学术论文 基于FPGA的FFT数字处理器的硬件实现
DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具,直接计算DFT的计算量与变换区间长度N的平方成正比.当N较大时,因计算量太大,直接用DFT算法进行谱分析和喜好的实时处理是不切实际的.快速傅里叶变换(Fast Fourier Transformation,简称FFT)使DFT运算效率提高1~2个数量级.本 ...

加密解密 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
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 ...
