运用vhdl硬件描述语言在quartus II开发环境下独立设计与实现了基于精简指令集的五级流水线CPU的设计与实现。该流水CPU包括：取指模块，译码模块，执行模块，访存模块，写回模块，寄存器组模块，控制相关检测模块，Forwarding模块。该CPU在TEC-CA实验平台上运行，并且通过Debugcontroller软件进行单步调试，实验表明，该流水线CPU消除了控制相关、数据相关和结构相关。(Using vhdl hardware description language development environment under quartus II design and implementation of an independent design and implementation of a five-stage pipeline RISC-based CPU' s. The water CPU include: fetch module, decoding module, execution modules, memory access module, the write-back module, the register set of modules, control relevant to the detection module, Forwarding module. The CPU in the TEC-CA experimental platforms, and single-step debugging through Debugcontroller software, experiments show that the pipelined CPU eliminates the control-related, data-related and structurally related.)

in this code very useful for designing real number concept

开发工具是quartus II 7.0以上版本，这是一个verilog语言的分频器设计，个人作业设计，供参考学习(verilog，quartus II 7.0)

适用于满足I2C协议的flash读/写操作程序，只需要设置要读/写的字节数，就可以直接使用！-Applicable to meet the I2C protocol flash read/write operations, only need to set to read/write number of bytes can be used directly!

针对AD9826驱动设计的Verilog代码，主要是配置ccd采样的设计(The Verilog code is designed for AD9826, to configuration ccd sampling )

1 前大灯可以随意打开和关闭； 2 当汽车左转弯的时候，前左转向灯闪烁，同时左后灯的3盏灯由右往左闪烁； 3 当汽车有转弯的时候，前右转向灯闪烁，同时右后灯的3盏灯有左往右闪烁； 4 当汽车减速或紧急刹车的时候，左后灯和右后等同时闪烁； 5 当汽车在左转弯的同时减速，则前左转向灯闪烁，左后灯的3盏灯由右往左闪烁，同时右后灯都点亮。 6 当汽车在左转弯的同时减速，则前右转向灯闪烁，右后灯的3盏灯有左往右闪烁，同时左后灯都点亮。 -a former headlamps can be opened and closed at will; 2 when the vehicle made a left turn when the former left to lights flickered. Left lights while the three lights flashing from right-go left; 3 when the vehicle is making a turn when a right turn to the former lights flickered. Right after the lights while the three lights are blinking right and left; 4 when the vehicle deceleration or when the emergency brake, Left and right after the lights blink, and so on; 5 when the vehicle made a left turn at the same time to slow down, and then to the left before the lights flickered. Left lights three lights flashing from right-go left, right after the lights are lit. 6 when a car made a left turn at the same time to slow down, and then right before the lights to flick

this a fpga sparttan 3e based project in which i have made a game based on vga interface . this file is the supporting file for keyboard interface and it also included a intro.vhdl file required for the startup animation file.-this is a fpga sparttan 3e based project in which i have made a game based on vga interface . this file is the supporting file for keyboard interface and it also included a intro.vhdl file required for the startup animation file.
