利用matlab，对偏振控制器进行仿真，最终在邦加球上进行显示(Using matlab, simulation of the polarization controller eventually be displayed on the Poincare Sphere)

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure.

用blockram实现移位寄存器，开发语言为verilog hdl(Shift register with blockram achieve the development language for the verilog hdl)

基于FPGA的频率测量，能测量方波信号的频率、占空比、相位差。范围100mHz~200MHz，精度0.0001Hz(The frequency measurement based on FPGA can measure the frequency, duty cycle and phase difference of the square wave signal. Range 100mHz~200MHz, precision 0.0001Hz)

说明：  FPGA控制AD7656和模拟开关实现36路模拟量循环采集(FPGA control AD7656 and analog switch to realize 36 channels of analog cyclic acquisition)
