vhdl经典源代码――键盘接口设计，入门者必须掌握

logic lock 的vhdl源码，altera平台适用。-logic lock the VHDL source code, altera platform.

用Verilog编写的以太网控制器，可以使用，里面是全部verilog源码(Ethernet controller based on Verilog, can be used directly, all verilog files)

用verilog写的CORDIC算法实现，很适合做超越函数的运算。通常用于实现正弦乘法，或者坐标变换。-The cordic arithmetic implemented by verilog is adapted to exceed function.It is usually used to implement sine multiplication or coordinate tuansform.

针对京微雅阁的CME300 FPGA教程，里面有几个例程，并附有源代码，初学者可尽快入门。(For Beijing micro Accord CME300 FPGA tutorial, there are a few routines, with source code, beginners can start as soon as possible.)

封装PS2接口驱动，用verilog编写！适用于键盘，鼠标等PS2接口的器件。(failed to translate)

在这里设计的是时分复用系统，就是要将三路8比特数据复用到同一信道上进行传输(Here is the design of time division multiplexing system, is to take the road three 8 bit data multiplexed onto the same channel for transmission)

10对于进入密码锁的按键，假设复位后七个灯显示0，使用sw1、sw2两个键输入，只要按sw1键，并使七个灯显示每秒速度加1的值，但释放sw1键后停止。

To increase simulation speed, ModelSim® can apply a variety of optimizations to your design. These include, but are not limited to, mergingprocesses, pulling constants out of loops, clock suppression, and signal collapsing. You control the level of optimization by specifying certain switches when you invoke the compiler.
