Graphics optimization for J2ME compatible mobile phones

Nowadays the high-resolution color screen becomes an inseparable component of modern mobile phones. Popular games, movies and 3D graphics capabilities require effective image rendering which is a task for both hardware and software engineers. The article is dedicated to the acceleration of low level graphics for J2ME based applications. It covers several aspects: algorithmic optimizations, use of embedded hardware accelerators, graphics performance measurement. Some high speed 2D graphics algorithms and most popular J2ME graphics benchmarks are considered. The issues related to the use of hardware graphics accelerators are discussed. And finally, practical results of low-level graphics optimization on Motorola phones are shown.
