关于基数分频技巧设计,基于VHDL语言,对实际设计有帮助

wm8731的使用，用于音频信号的采集或者产生(wm8731 use for audio signal acquisition or produce)

说明：  高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)

说明：  插值滤波器,用于音频解码调制解调,滤波器系数用移位相加实现(Interpolation filter, audio decoder for modulation and demodulation, filter coefficient shift combined with the realization of)

reversible Data Hiding in Encrypted Images by Reserving Room Before Encryption

本文提出了一种使用4根元素蝶形（m，n）计数器来降低硬件复杂度、延迟、功耗的传统加法器的使用方法。并针对FFT算法提出了一种改进的换向器，利用流水线传输实现了连续输入数据与信息的结合，减少了内存需求。
