用fpga芯片使用vhdl语言对AD转换芯片ADC0809进行控制(Using the fpga chip use language of VHDL AD transform chip ADC0809 control)

fpga控制da产生幅值频率可调的正弦波程序(the fpga Control da produce the amplitude adjustable frequency sine wave program)

基于fpga的物理不可克隆函数（PUF）模块的实现(A PUF Design for Secure FPGA-Based Embedded Systems)

SHIFT_8REG是8位的一个具有移位功能的寄存器，每一次数据打入都会从这个寄存器的最低位打入，并相应进行向左移位。 ODD_110BREG是一个3位的备份寄存器，寄存器中存放的是奇数帧的同步头，也就是110。 EVEN_9BHREG是一个8位的备份寄存器，寄存器中存放的是偶数帧的同步头，也就是10011011。这两个寄存器的初始值在系统一开始就打入。 -SHIFT_8REG is eight with a displacement of the functional Register, Each will enter the data from the register into the lowest point, and the left shift accordingly. ODD_110BREG is a three backup Register, the Register is stored in the odd frame synchronization head, is 110. EVEN_9BHREG 8 is a backup Register, which register is kept even the first frame synchronization, is 10011011. This register the two initial value of the system into a start.
