A complete HW/SW solution for SoC audio processing

Semiconductor IP vendors have traditionally competed on power, performance, and area, but having a full suite of supporting software is increasingly critical to enable SoC integration. is addressing this need by combining assets from several acquisitions over the past several years to grow from a supplier of primarily interface SIP into a more complete hardware/software solution vendor. The Synopsys DesignWare SoundWave subsystem integrates a single- or dual-core ARC audio processor with Sonic Focus audio enhancement software and IP for the audio codecs. An ARM AMBA AXI/AHB protocol interface facilitates integration of the audio subsystem into a SoC architecture.

By utilizing Synopsys Virtualizer prototyping tools with SoundWave, developers can perform pre-silicon integration of the audio software stack with their application software. Designers can use Synopsys’ HAPS (High-performance ASIC Prototyping System) -based prototyping system to perform system integration and hardware-software validation. Synopsys provides a library of certified codecs from Dolby Laboratories, DTS, SRS Labs, and Microsoft, along with open source Ogg Vorbis and FLAC formats. An audio plug-in software module for the open source GStreamer multimedia framework enables integration of subsystem software with host application software.
