使用Altera芯片实现对4个SAA7111A视频A/D芯片的采集控制，将图像数据存入同步FIFO-AL422B-use Altera chip to 4 SAA7111A Video A / D chip to control the collection, image data are stored in synchronous FIFO - AL422B

主要完成FIFO与DSP的接口，实现DSP与FIFO的接口控制-Completed for FIFO interface with the DSP, DSP and FIFO interface to achieve control
