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.)

作为一个简明的教程，主要宗旨是让初学者快速地了解FPGA/SOPC（可编程片上系统）开发的流程。-As a simple tutorial, the main purpose is to enable beginners to understand Express FPGA/SOPC (system on programmable chip) development process.

利用FPGA内核产生SPWM波，并且频率可调(The FPGA kernel is used to generate SPWM waves, and the frequency is adjustable)

利用拨码开关控制液晶显示器进行十进制数字显示。(DIP switches control the use of liquid crystal display to decimal figures.)

1024点FFT快速傅立叶变换，包含说明文档和VHDL源代码，16位输入/输出，带DMA功能，xilinx的ip-1024-point FFT fast Fourier transform, and includes documentation, VHDL source code, 16 input/output, with DMA function, the ip xilinx

Verilog代码，适合于初学者进行学习，是基于DE2平台的代码。(Verilog code, suitable for beginners to learn, is based on the DE2 platform code.)

说明：  卫星信道模拟器能够模拟卫星信道的传播特性，用于设备的通信调试，节 约研发成本。目前，很多卫星信道模拟器在参数设置上存在问题：有的参数难 以调节；有的采用上位机进行参数设置，通过上位机设置参数需要连接电脑， 适应性差。针对上述问题提出了一种基于FPGA可触控卫星信道模拟器，FPGA 作为算法实现和控制单元，通过控制触摸屏方便快捷的实现参数设置。(Literature of Satellite Channel Simulation Based on FPGA)

基于quartus的3-8译码器,可作为大型系统的译码器模块-Based on quartus a 3-8 decoder can be used as large-scale system decoder module

FPGA上的VERILOG语言编程。通过查找表实现直接数字频率合成。在主控部分通过键盘选择正弦波，方波，三角波，斜波，以及四种波形的任意两种的叠加，以及四种波形的叠加；通过控制频率控制字C的大小，以控制输出波形频率，实现1Hz的微调；通过地址变换实现波形相位256级可调；通过DAC0832使波形幅值256级可调；通过FPGA内部RAM实现波形存储回放；并实现了每秒100HZ扫频。(FPGA on the verilog language programming. Lookup table through direct digital frequency synthesis. In part through the control of the keyboard to choose sine, square, triangle wave, sloping wave, and four arbitrary waveform two superposed and the stack of four waveform; by controlling the frequency control word on the size, in order to control the output waveform frequency, 1 Hz to achieve the fine-tuning; Address transform through waveform phase adjustable 256; DAC0832 so through waveform amplitude adjustable 256; FPGA through internal RAM to the waveform storage intervals; and achieve a 100 per second sweep 9999.)
