  • 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.本文的目的就是研究如何应用FPGA这种大规模可编程逻辑器件实现FFT的算法.本设计主要采用先进的基-4DIT算法研制一个具有实用价值的FFT实时硬件处理器.在FFT实时硬件处理器的设计实现过程中,利用递归结构以及成组浮点制运算方式,解决了蝶形计算、数据传输和存储操作协调一致问题.合理地解决了位增长问题.同时,采用并行高密度乘法器和流水线(pipeline)工作方式,并将双端口RAM、只读ROM全部内置在FPGA芯片内部,使整个系统的数据交换和处理速度得以很大提高,实际合理地解决了资源和速度之间相互制约的问题.本设计采用Verilog HDL硬件描述语言进行设计,由于在设计中采用Xilinx公司提供的称为Core的IP功能块极大地提高了设计效率.

    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.
