cameralink总线接口代码，用于接收cameralink协议传输的图像数据。从芯片随路时钟域切换到系统时钟域。 做cameralink接口相关的图像采集系统可以参考。其中的ram是lattice工具生产的。-cameralink bus interface code for the image data receiving cameralink protocol transmission. Switching　chip clock domains with the way the system clock domain. Do cameralink interface-related image acquisition system can refer to.
