使用VHDL在CPLD上设计UART的一个项目

ATSC发送端部分，ATSC标准特有的TCM编码，共6个文件，包含tb文件，已通过仿真，没有问题，verilog代码-ATSC transmitter, the ATSC standard TCM unique coding, a total of six documents, tb-contained documents, had passed through simulation, no problem, verilog code

有用的数字钟设计文档，有秒表、闹钟等模块，希望对大家有用！(JUST LEARN FROM IT!!ENJOY!)

This verilog vga test circuit

用于实现FPGA硬件开发使用的加法器，需要注意的是用Verilog语言实现的(The adder used to realize FPGA hardware development needs to be realized in Verilog language)

Verilog经典实例.包括洗衣机红路灯、兹自动方麦基、等式子可用(Classic examples of Verilog. Including red street lights for washing machines, ZAM, equation availability)

Based on the verilog such as frequency meter accuracy, except for measuring frequency can also measure pulse width of empty measure than 32 counts of data through the simulation SPI serial output to SCM processing and display

说明：  ZYNQ中 PS 端 CAN接口的基本使用方法，并通过 CAN接口实现与 PC 端 CA N调试软件之间的数据接收和发送(The basic use method of PS end can interface in zynq, and the data receiving and sending with PC end can debugging software through can interface)

用VHDL语言设计四位全加器，有低位进位和高位进位。-VHDL language with four full-adder design, there are low and the high binary binary.

ADS7809是Burr-Brown公司推出的高精度AD采集芯片。它采用5V单电源供电,内含16位 逐次逼近寄存器,采样精度高,功耗小。 用Verilog实现其配置(ADS7809 is a Burr-Brown Introduces High Precision AD capture chip. It uses a single 5V supply, with 16-bit successive approximation register, sampling and high precision, low power consumption. To achieve its configuration with the Verilog)

? 熟悉IIC协议总线协议，采用IIC总线对图像采集传感器寄存器进行配置，并转换为RGB565格式。 ? 利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。 ? 利用 SDRAM 接口模块的设计，实现了刷新、读写等操作；为提高SDRAM 的读写带宽，均采用突发连续读写数据方式；并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。 ? 利用双线性插值方法实现对图像640×480到1024×768的放大操作。 ? 完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format. Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface. With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA. The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768. Complete the VGA display interface design.)
