Abstract：Inorder torealize effcient map application in embedded system with limited resources，this paper proposes a design scheme oflightweight two-dimensional electronic map display library.Throughthe layered architecture design， thedisplaylibraryis dividedintothreeparts： graphics interface，corealgorithmandrenderinglogic，whichisconvenientfor cro-platform porting.This paper focuses onthe underlyingrendering algorithm of electronic map.For resource-constrained scenarios，theoptimizationmethodsofBresenhamalgorithm，wide-lnealgorithm，anti-aliasingalgorithmandflingalgorithm areproposedAt thesametime，thedisplaylibraryusesdoublebufferingtechnologytoeffectivelyavoidthefickerproblem when the map isrefreshed.Multipleapplication scenarios tests show thatthegraphicsrendering effciencyof thedisplaylibrary is excellent，providing a feasible solution for electronic map applications on embedded devices.
