这是兼容的CPU 8051 VHDL语言，它不是一个侵权。上帝保佑！

应用背景对阵列的快速乘法的VHDL代码。作为主成分分析的项目的一部分，在FPGA。在可重构硬件平台实现的时候，该代码被开发，使矢量二进制乘法运算速度快。该程序可以在Xilinx Xise自如，可以在任何Xilinx FPGA编程。 ； ； ； ； ； ； ； ； ； ； ； ； ；关键技术该项目可开喜色从Xilinx。所有代码都是用VHDL和接收两个向量是mutliplied进行保存加法器加速增殖过程。最后的总和计算纹波进位加法器。操作数的长度是16位，结果是32位加一。

适用于FPGA的SOPC方面的元器件添加，如COMPNENT-Applicable to FPGA-SOPC area to add components, such as COMPNENT

本文通过大量的例子讲解VHDL。对于初学者来说是一本非常好的 教材-Based on the large number of examples of VHDL. For a newcomer it is a very good teaching

5对于进入密码锁的钥匙，假设复位后七节灯显示为" 0"，而使用sw1、sw2两个，则sw2-> sw1-> sw1-> sw2，则表示解锁右侧将导致七节灯显示为" 8"

看了好多网了，发现有2to4译码，3to8译码，今天我要用4to16译码，写完了就发了上来-saw a lot of net and found 2to4 decoding, 3to8 decoding, today, I must 4to16 decoding, finished on the fat in the ranks

数字时钟，包括流程图以及编码和完整的实验报告，内容详细丰富。(Digital clock, including flowcharts, and coding and a full lab report, detailed and rich.)

阿尔法贝塔滤波器，是卡曼滤波器的简化，比卡曼滤波器速度快。这是一个实例。(aplha-beta filter is filter that faster than kalman filter)

SRAM读写测试，每秒进行一次单字节SRAM读写，使用chipscope观察时序波形(SRAM read and write test, a single byte SRAM read and write every second, using chipscope to observe the timing waveform)

设计制作一个可容纳4组参赛者的数字智力抢答器，每组设置一个抢答按键； 电路具有一第一抢答信号的鉴别和锁存的功能。在主持人将系统复位并发出抢答指令后，若参加者按抢答键，则该组指示灯亮并用组别显示抢答者的组别。此时，电路具有自锁功能，使别组的抢答开关不起作用。 设置计分电路。每组在开始时预置成6分，抢答后主持人计分，答对一次加1分。(The design can accommodate a the Entrants digital intellectual Responder, each set answer in a key circuit has a first answer in the signal to identify and latch functions. Host to the system reset and sent the answer in instruction, participants answer in key, the group of the group light and display the answer in the group. At this point, the circuit has a self-locking function does not work in other groups to answer switch. Set Scoring circuit. Preset six points each at the beginning of the answer in scoring after the host, answer time, add 1 point.)

改变学习板上的2个电位器对应的2段模拟输入，实现模拟输入，学员观察数码管的数字变化情况,通过改D[4]的值，实现模拟输出.(Changing the learning board two potentiometers corresponding paragraph 2 analog inputs, analog inputs, digital tube digital trainees observe the changes, by changing D [4] value for analog output.)
