NEC mobile music chip
NEC has developed a new chip that enables mobile phones to play up to 50 hours of music, which beats out Apple's longest lasting iPod model by thirty hours of play time. The single-chip uPD99910 is the first in the company's new AP series of audio processors, integrating a central processing unit and digital signal processor dedicated to music playback, as well as an interface dedicated to copyright protection, according to Slashphone. The chip is designed to be a companion chip to an application processor, and incorporates an SD Memory Card interface while supporting Content Protection for Recordable Media (CPRM) technology. With the ability to integrate the aforementioned features on a single chip, the new processor allows manufacturers to improve mobile phone performance while reducing time to market and costs, according to the report.
