verilog code for counter four

计算机组成原理的CPU实验，基于quartus平台(CPU experiment of computer organization principle, based on quartus platform)

说明：  这是8位CPU的CVDL代码。CPU 的主要功能是执行指令，控制完成计算机的各项操作，包括运算操作、传送操作、输入/输出操作等。作为模型计算机设计，将重点放在寄存器级，采取较简单的组成模式，以尽量简洁的设计帮助学生掌握CPU 的基本原理。 此次设计CPU就是为了了解CPU运行的原理，从而完成从指令系统到CPU的设计，并且通过仿真对CPU设计进行正确性评定。(The main function of CPU is to execute instructions, control and complete various operations of computer, including operation, transfer operation, input / output operation, etc. As a model computer design, it focuses on register level and adopts a simpler composition mode to help students master the basic principles of CPU with a concise design as far as possible. This design of CPU is to understand the principle of CPU operation, so as to complete the design from instruction system to CPU, and evaluate the correctness of CPU design through simulation.)

一个可用的很不错的DDS 频率合成程序，用VHDL语言编写-Available is a good DDS frequency synthesis procedures, using VHDL language

:针对现场可编程门阵列(FPGA)芯片的特点,研究FPGA中双向端口I/O的设计,同时给 出仿真初始化双向端口I/O的方法。采用这种双向端口的设计方法,选用Xilinx的Spartan2E芯片 设计一个多通道图像信号处理系统。-: For field programmable gate array (FPGA) chip features of FPGA in the bi-directional port I/O design, the simulation is initialized at the same time two-way port I/O method. Using this design method of two-way ports, optional Spartan2E the Xilinx chip to design a multi-channel image signal processing system.

HDLC协议的FPGA实现，运用了VHDL语言，主要就是解封帧HDCL，平切添加了外部接口

说明：  传感器是一种检测装置，能感受到被测量的信息，并能将感受到的信息，按一定规律变换成为电信号或其他所需形式的信息输出，以满足信息的传输、处理、存储、显示、记录和控制等要求(Sensor is a kind of detection device, which can sense the measured information and transform it into electrical signal or other required information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.)

用VHDL编写的EPP通信协议，可以同时收发字节-EPP written in VHDL, communication protocol, you can also send and receive bytes

verilog实现的“BCD/七段译码器”。-verilog implementation " BCD/Seven-Segment Decoder."
