DirectFB在數(shù)控系統(tǒng)中的實現(xiàn)與應用

本文論述了DirectFB 在數(shù)控系統(tǒng)中的實現(xiàn)與應用。結(jié)合本課題數(shù)控機床控制系統(tǒng)的實際例子，討論了將GTK+界面程序移植到基于Framebuffer 的圖形庫系統(tǒng)DirectFB 上的重要性、具體實現(xiàn)過程和移植前后系統(tǒng)性能的比較。結(jié)果表明：DirectFB 在數(shù)控機床上的應用能夠使機床控制系統(tǒng)摒棄龐大低效的X
Window，提高系統(tǒng)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.
