Cadence Design Systems, Inc. (NASDAQ: CDNS), a global leader in electronic design innovation, today announced the Cadence® Tensilica® HiFi audio channel for Android (Androidä). As the industry's first Android-compatible technology for licensing digital signal processors (DSPs), Tensilica's Android-specific HiFi audio channel takes advantage of the latest improvements in the KitKat version to extend battery life in smartphones and mobile devices. This technology can reduce audio processing power by up to 14 times and double the playback time of smartphones. The KitKat audio channel was developed based on the efforts of the Low Power Android Alliance (LPAC), a consortium originally founded by Tensilica. The company is now part of the Cadence IP Group.

“Since battery life is so critical for smartphones and other mobile devices, Tensilica's dedicated HiFi audio channel for Android is critical to providing the most power-efficient Android audio solution.” Cadence Audio Voice Intellectual Property (IP) Marketing Director Larry Przywara said. “Up to now, Android devices also need to run audio on the main processor, or to process audio on a proprietary OEM offload frame that still needs to encode and decode the audio stream for processing by the main CPU. Next, Cadence worked with Google to develop an audio channel directly to Android DSP to solve this problem. To explore the full potential of this new Android KitKat feature, we developed Tensilica Android-specific HiFi audio channel for audio processing. It is now completely detached from the main processor, dramatically reducing power consumption, extending battery life and speeding time to market."

Tensilica's dedicated HiFi audio channel can be used with any of Cadence's HiFi audio/voice DSP IP cores. By pairing with these popular HiFi DSP cores, designers can take advantage of packages from more than 125 HiFi architectures that have been developed by Cadence and over 55 partners.
