Tel-Aviv and Santa Clara, CA - Sep 12, 2011 - EtherWaves has introduced a new version of ClearSignal, a software implementation for receiving and decoding DAB/DAB+/DMB/DMB SLS/DAB Data/DRM/MP4 broadcasts. It offers simultaneous decoding of audio and data services; dual-tuner, capable of decoding simultaneously two similar or different systems, such as DAB+ and DRM (or DMB); or decoding audio from one DAB audio service while decoding TPEG(2) on a DAB data service. It can provide also seamless audio switch-over when traveling between regions with different digital radio standards.
Previous versions of ClearSignal have been used by Tier 1 automotive infotainment makers, deployed in high-end German and Italian automotive cars and used by innovative SoC (system-on-chip) manufacturers.
The newly introduced version of ClearSignal is an RF-agnostic design, which broadens SoC designers' choice to immediately add digital radio capability to mobile devices, while keeping the required low power consumption. This ClearSignal implementation takes advantage of Tensilica's ConnX Vectra LX DSP engine and other architecture optimizations for achieving a typical DAB channel reception atc lock rates as low as 50 MIPS.
Tensilica's Xtensa data plane processors can be customized for applications such as digital audio, baseband DSP, and many other functions that most general-purpose processor cores can't efficiently perform.
