Aiming at the problem that the structure of traditional graphics processing unit（ GPU） user state driving for mobile terminals is not layered so that the software system has high coupling degree

which makes the module has low reusablity

a GPU user-mode driven layered design method for mobile terminals is proposed. The method divides the mobile GPU user state drive into an embedded graphics library（ EGL） design

an Open GL ES base library and an extended library for hierarchical design

thereby reducing the coupling degree of the driver software system

by limiting number of vertices to increase the drawing rate. The experimental results show that the time taken by the method to draw the cone is reduced

and the rate of drawing the graph is increased by 24. 24 %.
