DesignWare ARC Audio Solutions

Available separately or as part of the DesignWare SoundWave Audio Subsystem, which provides designers with a complete, pre-verified audio subsystem integrating hardware, software and prototyping for incorporation into system-on-chip (SoC) designs, the ARC audio solution includes the following hardware and software components:

  • High-performance DesignWare® ARC configurable cores deliver industry’s smallest area and lowest power
  • Highly optimized, thoroughly tested, production proven and certified audio and voice codecs
  • Post-processing audio enrichment software restores clarity, warmth, detail and realism from digitally compressed audio
  • Media streaming framework for easy creation of complex audio graphs, including a Blu-ray Disc™ reference design

Designed by Audio Professionals

Synopsys’ DesignWare ARC audio processors are the only ones in the market whose design was directly driven by both processor architects and audio engineering professionals. The DesignWare ARC audio solution is easily integrated into SoCs and fulfills today’s demanding processing requirements, and delivers an undeniably high-quality listening experience. 

Scalable Architecture

The DesignWare ARC audio processors range from the single-core AS211SFX processor to the high-performance AS221BD dual-core processor. Software that is written for a single core runs out-of-the-box on the dual-core processor. A multi-core media streaming framework that simplifies the partitioning and distribution of a complex use case with multiple audio codecs over such a dual-core system is also available.

Enable Capture and Playback of Studio Quality Audio

As consumers demand a better experience from their multimedia-capable devices that capture, share and playback audio, designers have to build SoCs that enable high-quality audio and allow extended operation. The DesignWare ARC audio solution is capable of delivering studio quality audio using post-processing technology and at the same time supporting long hours of playback time using active power management.
