摘　　要：设计了一种基于ARM的少数民族文字手写输入系统。以S3C2440A嵌入式微处理器为核心,对手写板的书写笔迹进行实时采集和预处理。利用USB接口与上位机通信,具有使用方便、传输速度快和稳定性高等特点,上位机将采集到的笔迹信息转换为汉字或图形等,显示并且保存,保证了书写的稳定性、准确性和实时性。China is a multi-ethnic,multilingual and multicultural country.Languages of ethnic minorities are a carrier to carry forward the heritage of national culture.ARM processor is widely used which provides a reliable guarantee for the real-time input,output,and editing of ethnic minority languages.According to the characteristics of functional diversity of the ARM processor,a handwriting input system of Minority Languages based on ARM is designed.The S3C2440A,an embedded microprocessor,is as the core of this system,which collects real-time data of handwriting pad and finishes preprocessing.The collected data is send to PC through Universal Serial Bus interface,which has convenience faster transmission speed and higher stability.Then the collected handwriting information is converted to a Chinese character or graphics to display and save,which can ensure the stability,accuracy and real-time of handwriting.
