USB的vhdl代码，具有很强的指导意义，对FPGA进行usb控制很有帮助！...

SDRAM控制器源码，内含完整的控制器verilog源代码和测试代码，超值哈。-This readme file for the SDR SDRAM Controller includes information that was not incorporated into the SDR SDRAM Controller White Paper v1.1.

SDRAM 控制器的多 CPU 系统的公断人将调度内存访问。

这是一个计算机组成原理综合性实验：设计8位cpu。该cpu是8bit的代码，包含有4个寄存器，一个存储器，还有alu以及控制器。一共可以实现16条指令。(This is a computer composition principle of comprehensive experiment: Design 8 cpu. The cpu is 8bit code contains four registers, a memory, as well as alu and controllers. A total of 16 instructions can be achieved.)

这个代码可以用来分裂振荡器的频率和产生 1 赫兹信号从 100 兆赫的 vhdl 语言使用的 Nexys 3 板。 这可以用作闹钟或数字时钟中的组件数秒。

FPGA流水线设计的资料，可以作为学习FPGA开发并行操作的一个经典教材，具有很好的指导作用。(FPGA pipeline design information can be developed as a learning FPGA parallel operation of a classic textbook, has a good guide.)

VHDL 快速参考手册，简要概括了VHDL，非常适合做开发参考-VHDL Quick Reference Guide, a brief summary of VHDL, is well suited to do the development of reference

用Verilog实现的交通信号灯控制，主干道和支路通行的时间不相等(Using Verilog implementation of traffic signal control, the trunk road and the slip is not the same passage of time)
