本文论述了DirectFB 在数控系统中的实现与应用。结合本课题数控机床控制系统的实际例子，讨论了将GTK+界面程序移植到基于Framebuffer 的图形库系统DirectFB 上的重要性、具体实现过程和移植前后系统性能的比较。结果表明：DirectFB 在数控机床上的应用能够使机床控制系统摒弃庞大低效的X
Window，提高系统的加工速度。

Abstract：In this paper, the author expounds the realization and implementation of DirectFB in Numerical Control System.Combined with the practical example of CNC machine tool of control system,it has discussed the importance of transplanting GTK+ interface program to DirectFB、the realization process and the amelioration of the transplanted numerical control system compares to the before.As a result,the application of DirectFB in CNC machine tool can abandon the inefficient X Window and improve the running velocity.
