基于VHDL的虚拟电子琴实现

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.)

用FPGA实现dct变换。verilog语言实现，在quartus9.0中验证，含整个工程(dct transform verilog language in quartus9.0 verify, with the entire project)

ahb to apb master verification

I2C端口的FPGA实现，网上较多，但发现不少有问题，这个是在网上代码的基础上修改过，验证可行。-I2C port FPGA, online more, but found that many problems This is a code on the Internet on the basis of the revised test feasible.

FPGA来实现数据采集，AD采用TI公司的THS1206，高速并行AD，内含16字FIFO，降低硬件复杂度。(FPGA to realize data acquisition, AD using TI company s THS1206, high-speed parallel AD, containing the 16-character FIFO, to reduce hardware complexity.)

8051单片机VHDL内核,内有说明,很详细,值得下载-8051 VHDL core, which has made it clear that, in great detail, it is worth downloading

低频数字式相位测量仪，数码管显示相位差，精度为0.1(Low frequency digital phase measuring instrument, digital pipe display phase difference )

7段数码显示译码器-seven of the digital display decoder

这是一个HDB3编码器，可以将普通的二进制序列转化为符合HDB3编码规则的双极性序列-This is a HDB3 encoder, can be transformed into an ordinary binary sequences in order to comply with the rules of HDB3 bipolar coding sequence

VHDL 源码模块，可以实现最经典原PWM，可以用于电源，电机的控制()
