代码用两种方法设计了一个基于多相滤波的内插器，低通滤波器采用128阶凯撒窗，内插倍数32，并且给定信号范围，验证了内插器的正确性，画出了内插前后信号的频谱。(The code design the interpolator based on polyphase filter using two methods.The low pass filter is 128 order Caesar window and interpolation multiple is 32.I give the range of the signal to verify the interpolator and plot the spectrum of the signal before and after the interpolator. )

? 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.)

一个具有“百分秒，秒，分”计时功能的数字跑表，可以实现一个小时以内的精确至百分之一秒的计时。 数字跑表的显示读者可以通过编写数码管显示程序来实现，本训练只给出数字跑表的实现过程。 读者还可以通过增加小时的计时功能，实现完整的跑表功能。-A " percentage of seconds, seconds, minutes," digital stopwatch timer can be achieved within an hour of precision to the hundredth of a second time. Digital stopwatch readers can display the digital display through the preparation of procedures to achieve, given the training is only the realization of the process of digital stopwatch. Readers can also function to increase hours of time to achieve full stopwatch function.
