介绍USB PHY接口中的UTMI接口， 对使用Verilog进行USB接口编程具有帮助。(This paper introduces UTMI interface in USB PHY interface. It is helpful for programming USB interface with Verilog.)

本例为DAC0832接口电路VHDL原代码-The DAC0832 Interface Circuit Example for VHDL source code

通信系统帧同步信号的设计与实现，巴克码识别器系统完整VHDL程序，本人课程设计，完全能正常运行，程序运行环境为Quartus II 7.2 (32-Bit)，win7系统。编译码模块、分频模块、门限设置模块、仿真电路和程序都有。相互交流，共同学习！！

说明：  基于labVIEW，控制电机等工作实例，程序基本完整(Based on labVIEW, control motor and other working cases, the program is basically complete)

包中包括, DW8051完整的Verilog HDL代码 两本手册: DesignWare Library DW8051 MacroCell, Datasheet DesignWare DW8051 MacroCell Databook 三篇51论文: 基于IP 核的PSTN 短消息终端SoC 软硬件协同设计 Embedded TCP/ IP Chip Based on DW8051 Core 以8051为核的SOC中的万年历的设计 (DW8051 is designed by synopsys, and its instruction cycle is 4 clock, which lead to about 3 times faster than Intel 8051 with the same oscillator frequency. I writed ram, rom, some other perpherals such as DES, RNG, and its testbench, and it worked all right!)
