摘要
介绍了一种利用USB传输视频数据的LCOS数码彩扩仪驱动设计方案。采用专用USB芯片实现图像数据传输,CPLD及SRAM实现视频数据的缓存,并由CPLD设计产生XGA信号驱动后端的LCOS控制芯片,最终实现了数码彩扩驱动系统的稳定输出,为实现LCOS数码彩扩系统提出了一种新思路,具有相当的实用价值。
This paper mainly introduces a solution of the output control system for LCOS photofinishing based on USB transfer. A USB microcontroUer is used for image data transfer. A CPLD is used to control the SRAM and to generate the XGA signal. This system, which can work well down, offers a new method for realizing LCOS photofinishing control system.
