这是一本国外的经典教材，讲述了现阶段所有数字信号处理的FPGA实现，从第二章讲述二进制的算法到现阶段数字信号处理的研究热点，基于FPGA实现！包括FIR，自适应滤波，纠错码，调制解调，加密，傅立叶变换等等。更难能可贵的是每个例子都有VHDL和Verilog代码！！(This is a classic foreign materials, described at this stage all the digital signal processing FPGA, from the second chapter about the binary digital signal processing algorithms to the current stage of research focus, based on FPGA implementation! Including FIR, adaptive filtering, error-correcting codes, modulation and demodulation, encryption, Fourier transform and so on. Even more valuable is that each case has a VHDL and Verilog code! !)
