通用串行异步收发器8251的Verilog HDL源代码,经过仿真验证。

脉冲宽度调制，VHDL代码编写，包括QUARTUSII和MODELSIM工程以及testbench-Pulse width modulation, VHDL coding, including QUARTUSII and ModelSim engineering and Testbench

PicoRV32 is a CPU core that implements the RISC-V RV32IMC Instruction Set. It can be configured as RV32E, RV32I, RV32IC, RV32IM, or RV32IMC core, and optionally contains a built-in interrupt controller. Tools (gcc, binutils, etc..) can be obtained via the RISC-V Website. The examples bundled with PicoRV32 expect various RV32 toolchains to be installed in /opt/riscv32i[m][c]. See the build instructions below for details.

4通道12位AD芯片 AD7862控制模块,VHDL源代码,适于单次转换采样,250K采样率.-4-channel 12-bit AD chip AD7862 control module, VHDL source code, suitable for single conversion sampling, 250K sampling rate.

结合截图，quartus2与ModelSim的联调的详细操作步凑，使初学者迅速上手-Combination of shots, quartus2 with the ModelSim FBI put together a detailed step-by-step operation, so that beginners get started quickly

基于verilog语言的数据选择器，包括数据选择器的测试模块 (verilog language based on the data selector, including data selection for the test module)

基于fpga的verilog实现ad及uart，并进行仿真验证(Verilog based on FPGA implements AD and uart, and carries out simulation verification)

 音频信号先经过由运放和电阻组成的50Ohm阻抗匹配电路以满足输入阻抗50 Ohm的系统要求，这样方便信号功率的计算。为了保证所处理的信号被不失真的采样，信号还要通过截止频率为10Khz的抗混叠低通滤波器。最后为了AD能正确的采样，信号还要通过信号抬高电路。 经过12位A/D转换芯片MAX144转换后的数字信号经由基于FPGA的NIOSII处理器进行FFT变换和处理，分析各个频率点的功率值，并将这些值显示在LCD上。 该源代码就是fft变换的源代码

说明：  Vivado是Xilinx最新的FPGA设计工具，支持7系列以后的FPGA及Zynq 7000的开发。与之前的ISE设计套件相比，Vivado可以说是全新设计的。无论从界面、设置、算法，还是从对使用者思路的要求，都是全新的。看在Vivado上，Tcl已经成为唯一支持的脚本，此文件是vivado是tcl命令的集合。(Vivado is Xilinx's latest FPGA design tool that supports development of FPGAs and Zynq 7000s in the 7 series and beyond. Compared with the previous ISE design suite, Vivado can be said that the new design. No matter from the interface, settings, algorithms, or from the user ideas, are new. Look at Vivado, Tcl has become the only supported script, this file is vivado tcl command collection.)

主要介绍，I2C总线主设备发送数据给从设备，代码实现是用Verilog语言实现的，对硬件设计者有很大好处(Introduces, I2C bus master to send data to the slave device, code is implemented in Verilog language, the hardware designer of great benefit)
