Design And Realization Of Graphics User Interface(GUI) Of DSP Embedded System

As embedded devices are used everywhere, the requirement of the high performance embedded graphics user interface(GUI) is damaned, but restricted by its poor hardware in old days. Owing to high signal processing capability of digital signal processor(DSP) , DSP has been applied in such fields as audio processing , image anilysis processing ,ect. Thus, the research on GUI of DSP embedded system is a great significance in practical application.The paper presents the basic concepts of embedded system and GUI , analyses the application requirments and significance of the project,and gives some introduction and comparision of corresponding projects domestic and abroad. Then,there is a study of the technology related to embedded GUI,including architecture, display driver, multi-task of embedded operating systemμC/OS-II,ect. The thesis demonstrate the design and realization on the architecture of GUI.The paper provides an embedded platform, which is comprised of an embedded micro controller DSP andμC/GUI of embedded operating systemμC/OS-II. This design...
