Automotive Mobile Audio Video

Designed as companion chip to application processor on mobile phones, single-chip uPD99910 integrates CPU and DSP that appropriate and optimize music playback function of application processor to conserve power and extended listening period. In addition to SD Memory Card interface, product provides interface dedicated to copyright protection media and supports Content Protection for Recordable Media (CPRM) copyright protection technology.

Enables 50 Hours of Continuous Music Playback on Mobile Phones

SANTA CLARA, Calif., March 20 / -- NEC Electronics America, Inc. today announced the launch of the first product in the company's new AP series of audio processors that enables 50 hours of continuous music playback on mobile phones. The single-chip uPD99910 audio processor integrates a central processing unit (CPU) and digital signal processor (DSP) dedicated to music playback and an interface dedicated to copyright protection media.

Designed to be a companion chip to an application processor, NEC Electronics' uPD99910 device appropriates and optimizes the music playback function of the application processor, incorporates an SD Memory Card interface and supports Content Protection for Recordable Media (CPRM) copyright protection technology whose SD-Audio function enables music data to be downloaded and played without copyright infringement. The power saved by having the playback-dedicated CPU and DSP operate in place of the application processor allows 50 hours of continuous music to be played back using existing resources such as user interface software. By having these features integrated on a single chip, the new processor allows manufacturers to enhance mobile phone performance while reducing time to market and costs.
