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.
