Tensilica Inside

The WiFi in the new Nitendo DSi

Solving the "More Features and Longer Battery Life" Dilemma

The crunch is on to add as many features as possible to mobile entertainment products, yet keep extending battery life. Tensilica's processors provide high image and video quality, wireless connectivity, and outstanding audio performance for everything from MP3s to multi-channel playback of pre-recorded media. That's why so many companies picked Tensilica's cores for dataplane processing in their mobile entertainment designs. Designed for low-power applications, our processors can be used for:

• Audio processing
• Video and graphics processing
• Camera functions
• Wireless connectivity
• Security
• Embedded control processing

Audio Processing

Consumers want high-quality audio from their mobile entertainment devices, so whether your device is going to decode an MP3 stream or Blu-ray Disc high-quality audio, you need an audio processor capable of accurately reproducing sound coded in multiple formats. The HiFi 2 Audio Engine has the lowest power MP3 playback on the market, enabling up to 200 hours of playback time for portable media. The HiFi 2 Audio Engine also supports all popular Dolby and DTS home entertainment standards for mobile TV and Blu-ray Disc players. Read more about our HiFi 2 audio processor, which has been designed into millions of mobile consumer products. And our Xtensa processors can be used for noise reduction, voice processing, and other signal processing tasks.

Because the HiFi 2 Audio DSP is so efficient, codecs can run at low frequencies and additional processing power is available for custom audio codec ports or audio pre- and post-processing, such as noise reduction, echo cancellation, 3D surround effects or voice processing.

Video and Graphics Processing

Xtensa processors for video post processing for tasks such as scalars, de-interlacers, filters, etc. If you're designing an HD video block, Tensilica's processors are ideal companion control processors. And you'll need a 3D graphics engine to run the menus and games on portable entertainment devices. Tensilica's processors have been designed into 3D engines by nVIDIA.

Camera Functions

Consumers like devices that include many functions, so most portable entertainment devices now include a high-quality camera. Tensilica's Xtensa processors are used by companies such as Olympus, Sony, Nethra, and other industry leaders for camera functions. Ideal uses include image processing, filtering, and any heavy data signal processing as well as control.

Wireless Connectivity

Many mobile entertainment devices rely on Internet connections so consumers can stream games, download and play music, and view DTV, pictures, or videos. The wireless connectivity needs to be very reliable. Companies like WiLinx are using Xtensa processors for ultrawideband designs. Tensilica's processors can be customized to exactly match the requirements of the wireless connections, delivering a very small, low-power solution.

Many mobile entertainment devices rely on Internet connections so consumers can play games over the Internet, view moble digital TV, download pictures or stream videos and music. With the increased demand for content transmissions, these wireless connections need to enable ever increasing bandwidth. Tensilica is being used by leading companies such as NEC, Fujitsu, and Atheros to deliver the large increase in bandwidth processing and multiformat radio processing.

Security

It's essentail to implement complex security algorithms in a processor in case these algorithms needs to be changed. These algorithms are often used for encryption throughout the system, so engineers can't pirate copyrighted media. Commercially distributed music contains Digital Rights Management (DRM) features that require complex decryption in portable devices. Tensilica's Xtensa processors are perfect for a programmable solution so that, as standards change, you don't need to respin the chip.

Embedded Control Processing

Tensilica's processors can provide the embedded control you need for the various subsystems in your device. From the Diamond Standard controllers to the customizable Xtensa processors, we can provide the level of processing power and even operating support that you need.
