Abstract: Aiming at the strong capability of Blackfin processors on multimedia, this paper researches the techniques related to Graphic User Interface(GUI). It implements an embedded GUI system based on uClinux, which achieves smaller size and higher performance. It is suitable for electronic products requiring display of high definition. It compares the performance between the GUI with Microwindows. Results show that the development of embedded applications, especially multimedia products with high performance can benefit greatly from the implementation of the GUI.
