Digital entertainment systems - which encompass a broad range of applications, including smart phones, set-top boxes, MP3 players, DVD players and recorders, game consoles, and digital cameras - have become the driving force behind the expansion of the semiconductor market, outstripping even PCs. Consider, for example, that in 2003, smartphones represented about 3 percent of the 500 million mobile phones sold worldwide, with analysts expecting them to grow at triple-digit year-over-year rates. Moving beyond the voice-centric model, more than half of the 600 million mobile phones sold in 2004 included a color display and digital camera. The implementation of more advanced features such as accelerated 2D and 3D graphics, videoconferencing, mobile multimedia, and games has raised the performance requirements of these model. The Embedded Microprocessor Benchmark Consortium's DENBench suite of digital media benchmarks provides a spectrum of tools for assessing and refining the video and audio performance of digital devices.
