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. Synopsys 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 mixed-signal 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) FPGA-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.
