LDPC最小和算法校验节点更新单元CNU verilog设计

单周期16位CPU的设计,我们的计算机组成原理课设，可以实现R型、I型和J型指令，内有报告和指导书(Single-cycle 16-bit CPU design, our Principles of Computer Organization class set, you can achieve R-type, type I, and J-type instructions, reports and instructions)

本程序是在AWGN下的LDPC码的仿真程序，本程序优点是译码效率高，速率很快，可以仿帧数很大的图。(the decoder for LDPC under the AWGN channel)

说明：  stm32f103 usart 控制led灯(STM32F103 USART control LED)

伺服电机主控制模块输入输出特性的简单模拟实现，输入目标电压及反馈的当前电压，输出对电机的控制脉冲波形(The simple simulation of the input and output characteristics of servo motor main control module, the input is target voltage and feedback is the current voltage, the output is the motor control pulse waveform)

载波同步，costas环，基于Verilog的载波同步环(Carrier synchronization, costas ring, based on Verilog carrier synchronization ring )

基于ISP的交通灯设计，实现了各路状态转换、警察控制、行人请求功能。(ISP traffic light design, to achieve the brightest state transitions, police control, pedestrian request feature.)

最大值求解是利用System Generator平台实现的比较方便不用自己写verilog代码就可以在Xilinx平台下使用，非常方便实用！

The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The 720-channel source driver has true 6-bit resolution, which (The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data.

该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)
