DATA SHEET .onsemi. Audio Processor for Portable munication Devices Bela Signa 300 Introduction Bela Signa 300 is a DSP- based mixed- signal audio processing system that delivers superior audio clarity without promising size or battery life. The processor is specifically designed for monaural portable munication devices requiring high performance audio processing capabilities and programming flexibility when form- factor and power consumption are key design constraints. The 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 puting 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. Bela Signa 300 is supported by a prehensive 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. Key Features - Flexible DSP- based System: a plete DSP- based, mixed- signal audio system consisting of the CFX core, a fully programmable, highly cycle- efficient, dual- Harvard architecture 24- bit DSP utilizing explicit parallelism; the HEAR configurable accelerator for optimized signal processing; and an efficient input/output controller (IOC) along with a full plement of peripherals and interfaces, which optimize the architecture for audio processing at extremely low power consumption - Ultra- low-...
