硬件描述语言

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)

开关电源中用单片机产生可调电压控制PWM波程序,ADC0832读取输出电压(Single-chip switching power supply using adjustable voltage control PWM wave generation process, ADC0832 read the output voltage)

由于在网上很难下载到EDA技术－窦衡的PPT，所以本人经过学习后做成word，供大家下载。只针对VHDL语言部分和所有的程序。-Because the Internet is difficult to download to EDA technology- Douheng of the PPT, so I made after learning after the word, for all to download. Only for part of the VHDL language and all the procedures.
