BelaSigna® 300 is a DSP−based mixed−signal audio processing system that delivers superior audio clarity without compromising size or battery life. ¡El processor is specifically designed for monaural portable communication devices requiring high performance audio processing capabilities and programming flexibility when form−factor and power consumption are key design constraints. ¡El efficient dual−MAC 24−bit CFX DSP core, together with the HEAR configurable accelerator signal processing engine, high speed debugging interface, advanced algorithm security system, state−of− the−art analog front end, Class D output stage and much more, constitute an entire system on a single chip, which enables manufacturers to create a range of advanced and unique products. The system features a high level of instructional parallelism, providing highly efficient computing capability. It can simultaneously execute multiple advanced adaptive noise reduction and echo cancellation algorithms, and uses an asymmetric dual−core patented architecture to allow for more processing in fewer clock cycles, resulting in reduced power consumption. BelaSigna 300 is supported by a comprehensive suite of development tools, hands−on training, full technical support and a network of solution partners offering software and engineering services to help speed product design and shorten time to market.
