VHDL串并转换源程序，可以实现信号在串行和并行间的转换。-SERDES VHDL source code, you can achieve signal at between serial and parallel conversion.

基于VHDL语言，实现对ADC0809简单控制,ADC0809没有内部时钟，需外接10KHz~1290Hz的时钟信号，这里由FPGA的系 --统时钟（50MHz）经256分频得到clk1（195KHz）作为ADC0809转换工作时钟。 -Based on VHDL ADC0809 simple control, ADC0809 no internal clock, an external clock signal of 10KHz ~ 1290Hz here by the Departm

ASK调制VHDL程序及仿真:基于VHDL硬件描述语言，对基带信号进行ASK振幅调制-ASK modulation and VHDL simulation: based on the VHDL hardware descr iption language ASK amplitude modulation, the baseband signal
