HDMI接口编解码传输模块ASIC设计_刘文杰
? 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.)

add_noisem
把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92,其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等,在信号处理中往往需要把库中的噪声叠加到信号中去,而噪声的采样频率与纯信号的采样频率往往不一致,需要采样频率的校准。
(The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

Verilog数控分频器的设计
分析参考代码中的各语句功能、设计原理、逻辑功能,根据图1的波形提示,编写相应的Testbench文件代码,并用Modelsim进行仿真(仿真可以跳过时钟分频到100hz进程)。
在此基础上进行硬件验证。实验方法为:将clk接20Mhz时钟信号,rst_n接核心板开关S1,fout接发光二极管SD0,预置值d从DKA0-DKA7输入,改变d的输入,从发光二极管SD0判断输出信号的频率。
