The DesignWare SoundWave Audio Subsystem provides designers with a complete, pre-verified audio subsystem consisting of hardware, software and prototyping for integration into system-on-chip (SoC) designs. Supporting 2.1 to 7.1 audio streams at 24-bit precision, the SoundWave Audio Subsystem meets the demanding performance requirements of todays audio applications such as digital TVs, set-top boxes, Blu-ray Disc, speaker bars, media players, portable audio and tablets. The SoundWave Audio Subsystem consists of DesignWare 32-bit ARC audio processors, standard digital interfaces, analog audio codecs, and a complete, ready-to-use software environment that seamlessly plugs into the host application and includes a comprehensive library of software audio codecs that support the latest formats from Dolby, DTS and SRS. The SoundWave Audio Subsystem includes both virtual and FPGA-based prototypes to accelerate software development and validation of the full system. By integrating multiple IP blocks together with software in a pre-verified subsystem, Synopsys gives designers a configurable, SoC-ready audio solution that significantly reduces their SoC design and integration effort, lowers design risk and accelerates time-to-market.


  • Complete, pre-verified hardware implementation supports 2.0 to 7.1 audio streams with 24- bit precision to meet latest audio standards
  • Ready-to-use software environment includes all software needed to support a broad range of audio applications and enables designers to quickly integrate the subsystem into their host application
  • Single and dual-core 32-bit DesignWare 32-bit ARC audio processors implementations optimized for processing multiple high-definition, multi-channel audio streams in parallel
  • Digital audio interfaces such as S/PDIF and I2S provide multi-channel input and outputs
  • Analog audio codecs provide high-quality connections for line inputs/outputs, microphones, loud speakers and headphones with dynamic range of 96dB
  • Comprehensive library of software audio codecs including support for latest standards from Dolby, DTS, SRS Labs and Microsoft
  • Audio plug-ins based on the industry-standard GStreamer multimedia software enable developers to quickly integrate audio subsystem software into their host application
  • Virtual and FPGA-based prototypes enable complete hardware-software integration and system validation
  • Easy to use configuration tool enables a complete subsystem to be configured in hours instead of weeks
  • Configurations as small as 0.21mm2 consuming 0.30 mW in a 40-nm process technology
  • Available SoC integration services help implement and optimize the subsystem in the context of the full chip
