Synopsys Introduces Dolby MS11 Decoder for DesignWare ARC Audio Processors
Support for Dolby Laboratories' Multistream Decoding Expands Portfolio of ARC Audio Codecs

MOUNTAIN VIEW, Calif., Aug. 12, 2013 /PRNewswire/ --


  • Dolby MS11 decoder certified by Dolby Laboratories to run on single- and dual-core ARC audio processors
  • Supplies full Dolby metadata support and decodes all audio formats required to match global and local broadcast standards including Dolby Digital Plus, Dolby Digital and Dolby Pulse
  • Allows pass-through of the main audio directly for output over HDMI® interfaces. Extends broad portfolio of fully certified and thoroughly tested audio codecs optimized for use with Synopsys ARC processors

Synopsys, Inc. (Nasdaq: SNPS), a global leader providing software, IP and services used to accelerate innovation in chips and electronic systems, today announced the availability of the Dolby® MS11 Multistream Decoder optimized for its DesignWare® ARC® AS211SFX and AS221BD audio processors. The MS11 Multistream Decoder provides television and set-top box manufacturers with a single-package technology solution for decoding all premium audio formats, including Dolby Digital Plus, Dolby Digital, Dolby Pulse (AAC LC, HE AAC, and HE AAC v.2). The Dolby MS11 decoder has been certified by Dolby Laboratories for the ARC AS2xx family of single- and dual-core audio processors, allowing Synopsys to offer a complete and proven solution that simplifies the development, testing and qualification of Dolby MS10/MS11-enabled devices while ensuring optimal compatibility with the worldwide installed base of home theater systems and future broadcast audio standards.

"Dolby is committed to providing the best technology solutions to ensure maximum efficiency, consistency, and compatibility for the diverse needs of the global broadcast ecosystem," said Mathias Bendull, senior director for broadcast consumer audio at Dolby Laboratories. "With Dolby MS11, the DesignWare and ARC audio processors will enable Synopsys's customers to deliver a richer, high-quality sound experience in their audio-enabled devices."

Synopsys' DesignWare ARC audio solution is a scalable hardware and software IP solution that includes codecs, audio processors, media streaming frameworks and post-processing software. The Dolby MS11 decoder for ARC can be used on either a single-core AS211SFX or dual-core AS221BD ARC audio processor, which gives designers the flexibility to configure designs for specific applications and performance requirements. ARC audio processors incorporate dual MAC (Multiply-Accumulate) execution units for efficient audio processing, resulting in a processor load as low as 56 MHz for 100 cycles of latency from system memory and leaving sufficient bandwidth for additional audio software. Additionally, the ARC-optimized Dolby MS11 decoder enables a wide range of post-processing capabilities by including full access to the decoded audio streams. One key application is the ability to apply Dolby Volume to a decoded 5.1 Dolby Digital Plus stream and then re-encode the stream to Dolby Digital for output to a home theater. Synopsys' entire family of DesignWare ARC audio codecs is optimized for performance and ease of integration into SoCs and is fully compliant to audio industry standards such as AMR-WB+, MPEG-4 aacPlus v2, FLAC, WMA 10 Pro, Dolby Digital Plus and DTS-HD Master Audio.

"The growth in available ARC audio codecs demonstrates the scalability of our end-to-end DesignWare ARC Audio solution and our support for the latest audio technologies," said John Koeter, vice president of marketing for IP and systems at Synopsys. "Availability of Synopsys' Dolby MS11 decoder software for DesignWare ARC audio processors continues the expansion of our audio IP portfolio and provides IC and consumer product manufacturers with a single certified decoder that reduces the complexity and cost of integrating multiple audio technologies into new receivers."
