与单片机相比，用CPLD/FPGA器件更适合于直接对高速AD采样控制。本实验接口器件为ADC0809，根据ADC0809的工作时序使用CPLD产生该控制信号，CPLD启动AD转换后，得到的数据送至单片机并在PC机及数码管上显示AD转换结果。(Compared with the microcontroller, CPLD/FPGA devices more suitable for direct sampling control of high-speed AD. The interface of the experimental device for the ADC0809 ADC0809 Timing CPLD is used to generate the control signal, the CPLD to start the AD conversion, the data sent to the microcontroller and the AD conversion result on the PC and digital tube display)

this project is based on jk and t flip flop using vhdl.this is the 100 correct code,reference is taken from book digital electrionics written by anand kumar.please use quatrus to access this code.this code can be used for the final year project for engineering. Here dataflow techniques and behavioural techniques are used. -this project is based on jk and t flip flop using vhdl.this is the 100 correct code,reference is taken from book digital electrionics written by anand kumar.please use quatrus to access this code.this code can be used for the final year project for engineering.
