21ic News Synopsys, Inc. announced today that it has introduced its complete set of integrated hardware and software audio IP subsystem DesignWare® SoundWave Audio Subsystem for system-on-chip (SoC) design. Synopsys' SoundWave audio subsystem is fully configurable and supports 24-bit audio from 2.0 to 7.1 channels for a wide range of audio applications such as digital TVs, set-top boxes, Blu-ray disc players, portable audio devices and tablets. Demand.

The SoundWave audio subsystem consists of the following components: a 32-bit DesignWare ARC® audio processor, a standard digital interface, an analog codec, a software audio codec synthesis library that supports the latest formats from Dolby, DTS and SRS; A complete software environment that integrates the media flow framework. The SoundWave audio subsystem also includes both virtual and FPGA-based design prototypes to help engineering teams accelerate software development and validation of the entire system. By integrating multiple IP unit modules with software to become a pre-verified audio subsystem, Synopsys provides designers with a set of SoC ready-to-use audio solutions that significantly reduce their SoC design and integration. The workload, while reducing design risks and shortening time to market.
The increasing use of multi-channel audio content in audio applications and its higher sampling rate adds to the complexity of many consumer-oriented SoCs today. In addition, the new audio standard requires more signal processing and bandwidth to provide high quality sound reproduction over a larger range of audio formats. The use of a dedicated audio subsystem allows audio processing tasks to be offloaded from the host processor, thereby reducing design complexity and improving SoC performance and efficiency.
“By 2014, the average number of IP modules integrated on a SoC is expected to approach 120. Designers need solutions that can help them significantly reduce the workload in IP integration and management of those moduleâ€, Market Research Rich Wawrzyniak, senior market analyst at Semico Research, said. "With a complete, pre-validated IP subsystem, because it includes hardware and software for use with IP, designers can solve their design problems at the chip level rather than at a single module level. Through the DesignWare SoundWave audio sub- System, Synopsys has opened up new areas in the IP industry that will enable electronics developers to innovate faster."
Built-in hardware
The SoundWave audio subsystem features an ARC single-core or dual-core, energy-efficient 32-bit audio processor optimized for parallel processing of multiple HD, multi-channel audio streams. The audio subsystem includes I2S and S/PDIF digital interfaces for off-chip audio connections and high-bandwidth on-chip connections such as HDMI. The system interface of the ARM® AMBA® 3 AXITM/AHB protocol makes it easy to integrate into the SoC architecture. The analog audio codec provides a high quality audio connection for line inputs and outputs, microphones, speakers and headphones. An easy-to-use configuration tool allows designers to quickly select options such as the number of channels and the number of audio interfaces, making it a few hours to configure a complete audio subsystem instead of a few weeks of manual completion. Synopsys also offers SoC integration services to help customers integrate subsystems into their chips or customize subsystems to meet their unique application needs.
Special software
The SoundWave Audio Subsystem provides a complete, ready-to-use software environment that includes support from Dolby Labs (such as Dolby Digital Plus and TrueHD), DTS (such as DTS HD Master Audio), SRS Labs (such as TruSurround HD4 and TruVolume) and Microsoft's (such as WMA 10 Pro) audio codec for the latest multi-channel audio formats, including popular open source formats such as Ogg Vorbis and FLAC. The SoundWave Audio Subsystem's built-in media stream framework embeds decoders, encoders, and audio post-processing functions such as volume control, equalizer, and surround balance. This framework allows software codecs and post-processing software to be easily instantiated into subsystems. An audio plug-in based on industry-standard GStreamer multimedia software enables developers to quickly integrate audio subsystem software into their main application software.
Virtual and hardware prototypes Developers of software-rich electronic devices, especially those that will target mobile and consumer markets, must not only respond to the rising software content of their designs, but also face the development of software. The challenge of integrating it with hardware. To ease the software development effort, a virtual prototype of the SoundWave audio subsystem based on Synopsys' VirtualizerTM ensures early integration of the audio software stack and application software, which was implemented months before the film was released. The audio subsystem's HAPS® FPGA-based prototyping solution enables instant software development and provides an extensible platform for fast, system-wide integration and verification.
“Because designers have evolved their methodology to cope with the growing complexity of SoC designs, the form of IP delivery must evolve,†said John Koeter, vice president of IP and systems marketing at Synopsys. “Designers need the best combination of software and hardware to meet the performance, cost, power, and schedule requirements of their designs. The DesignWare SoundWave audio subsystem provides a complete end-to-end, proven, off-the-shelf audio subsystem. Designers have significantly shortened their time from concept to implementation."
Availability The DesignWare audio subsystem is now available to early adopters and will be available in April 2012.
