基于CPLD的数码冲印输出控制系统

The control system of output of digital photofinishing based on CPLD technology

介绍了激光数码冲印这一彩扩影像产业的新技术。在数码冲印系统中,输出控制系统部分具有重要的意义。设计了一种基于CPLD(复杂可编程逻辑器件)技术的输出控制系统,并完成了相应的软硬件配置。其中的高速缓存控制部分保证了打印过程中数据传输的连续性和流畅性,达到了满意的打印效果,具有相当的实用价值。

This paper briefly introduces the laser digital color photofinishing, which is the most advanced and popular technology of the color projection and imaging industry. The part of control of the output plays an important role in the whole system. A new project of the control system based on CPLD technology is designed and the hardware and software configuration is accomplished. With the good work of the high-speed FIFO the data are transferred smoothly and continuously and the satisfactory printing effect is achieved.
