A universal solution of an embedded multitasking GUI System

Abstract

This paper presents a universal architecture of an embedded GUI system, which makes it possible to satisfy multitasking requirements, and provide efficient performance on diverse platforms in a simple way. It focuses on the infrastructure, involving the hierarchical architecture, message-driven mechanism, multitasking scheduling policy and windowing management. Designing by means of OO-based methodology, the whole system is portable and flexible. Moreover, this solution has been verified through the prototype implemented on PXA225 and DeltaOS.
