摘　　要：介绍了以东南大学国家专用集成电路系统工程技术研究中心自主设计的基于ARM7TDMI的SEP3203处理器芯片为硬件平台,在μClinux应用程序中移植LCD驱动和GPC图形库的方法和具体的实现步骤.验证结果表明:可以在LCD上实现画点、画线(水平、竖直、斜线)、画圆、画矩形、画椭圆等绘图操作和中英文字符的输出,方法简单,并节省了代码空间.Based on the embedded processor GARFIELD which is designed by the National ASIC System Engineering Center itself, this paper introduce the method and the detailed realizing steps of porting the LCD driver and GPC library in the application program of the μClinux. As a result of verification, the method has saved the space of code and achieved the production level requirement, and simply realized drawing basic graphics, such as dot, line （horizontal, vertical, sloped）, circle, rectangle, ellipse and so on, and it can also realize the outputting of the English/Chinese characters.
