combinational circuits code in vhdl

有实验结果,用MOSIN6编写的,是Verilog HDL语言实现的. 练习三 利用条件语句实现计数分频时序电路 实验目的： 1. 掌握条件语句在简单时序模块设计中的使用； 2. 学习在Verilog模块中应用计数器； 3. 学习测试模块的编写、综合和不同层次的仿真。 练习四 阻塞赋值与非阻塞赋值的区别 实验目的： 1． 通过实验，掌握阻塞赋值与非阻塞赋值的概念和区别； 2． 了解阻塞赋值与非阻塞赋值的不同使用场合； 3． 学习测试模块的编写、综合和不同层次的仿真。 -The experimental results are used to prepare MOSIN6 is achieved Verilog HDL language. Practice the use of conditional statements to achieve the three sub-frequency timing circuit count experimental purposes: 1. Have conditional statements in the simple timing of the use of modular design 2. Learning modules in the Verilog Application of counter 3. to learn the preparation of the test module, integrated and different levels of simulation. Practicing the four blocking assignment with the distinction between non-blocking assignment experimental purposes: 1. Through experiments, hands blocking assignment with the concept of non-blocking assignment and distinction 2. Understanding of blocking and nonblocking assignment assignment usi

請設計一個8位元移位暫存器，規格如下： 當控制線S1，S2輸入為00時，平行載入； 當控制線S1，S2輸入為01時，在一時脈內向右shift 1位元； 當控制線S1，S2輸入為10時，在一時脈內向右shift 2位元； 當控制線S1，S2輸入為11時，在一時脈內向右shift 3位元 (Serial Adder)

说明：  verilog语言书写，单周期CPU源码(single period CPU)

这个代码主要实现了基于VHDL的关于TV方面的功能。(This code is the main achievement of the VHDL about aspects of the function based on TV.)

用verilog编写的科斯塔斯环，希望有帮助(Costas loop written in verilog helpful)

说明：  本文研究的IIC总线控制器具有如下特征 1.兼容飞利浦I2C标准，以主机模式与外围设备进行数据通信，对IIC从机模型进行读/读，读/写，写/写，写/读[18]。 2.多主操作 3.软件可编程时钟频率 4.时钟拉伸和等待状态生成 5.软件可编程确认位 6.时钟同步设计 7.仲裁中断丢失，自动转移取消 8.开始/停止/重复启动检测/确认生成 9.总线忙检测(The IIC bus controller studied in this paper has the following characteristics. 1. Compatible with Philips I2C standard, data communication between host mode and peripheral devices, read/read, read/write, write/write, write/read for IIC slave model [18]. 2. Multiple Main Operations 3. Software programmable clock frequency 4. Clock stretching and waiting state generation 5. Software Programmable Confirmation Bit 6. Clock Synchronization Design 7. Loss of arbitration interruption and cancellation of automatic transfer 8. Start/Stop/Repeat Start Detection/Verification Generation 9. Bus busy detection)

用全加器设计8位运算器逻辑电路图 2、根据逻辑电路用 VHDL编程实现 3、调试编译通过后，仿真 (this file can help you learn the design of cpu)

测量周期,此程序已经在EP2C板子上成功实现(mesure cycle)
