With the temptation of $ 10 billion, Tensilica quietly targets the Chinese audio market

Tensilica recently added China's DRA standard to its library of over one hundred audio codec algorithms. This is a technology dedicated to adding high-fidelity audio digital signal processing solutions to mobile devices. The company wants to pass this time Add standards and concentrate its future development and growth on China's huge electronic market.

Tensilica expects that by 2014, shipments of high-fidelity DSP audio chips entering the mobile phone field will reach a staggering 1 billion, which is far ahead of the current 300 million. Tensilica's software partners see this market as Dolby, Acoustics, DTS, SRS, Qsound, Sensors, Dynamic Volume, AM3D and Arkamys.

Currently, Tensilica's audio chip sales are US $ 300 million, and are expected to reach US $ 1 billion in 2014, and the global market in 2016 will reach US $ 10 billion

China designated DRA as the international audio coding standard in 2009.

Chris Rowen, CTO of Tensilica, said: The world has changed the way we use our ears and mouth. Audio is doing what the video did two or three years ago. Today, people demand the same high-quality audio experience as they do for movies and sports, and they also pursue the same in mobile devices.

In addition to the requirements for the expansion of the looped stereo stage in entertainment, technologies such as sound speed control and noise cancellation that use microphone array processing also have new demands in terms of sound processing.

"We are only now beginning to tap the potential of high-fidelity audio for mobile devices, and we have just sold the 10 billionth product in high-fidelity audio for mobile devices."

According to Rowen, the requirements for sound not only exceed battery technology, but also exceed the limitations of Moore's Law on audio chips. This statement is gradually becoming familiar. Therefore, Tensilica and other important audio suppliers need the innovation zone to maintain a balance between the two, because engineers cannot expect Moore's Law to provide an additional process law that meets their needs. This law is proportional to meet higher demand.

Now, smartphones need audio DSPS of about 200MHZ to process sound and music, but according to Rowen, in two to three years, designers need at least 600HMHZ technology to deal with higher bandwidth audio coding, broadband network voice, audio pre and post audio Processing and adaptive processing at the receiving end of the call to improve fidelity.
