1. What is an IP subsystem?
A: An IP subsystem integrates multiple proven IP module units and a complete software solution into one integrated design to perform a system-level function such as audio, video and image. The IP subsystem contains interactive hardware and software that are fully optimized, tested, and verified to implement this system-level functionality.
2. What is the DesignWare® SoundWave Audio Subsystem?
A: The DesignWare SoundWave Audio Subsystem is a complete, pre-verified audio subsystem solution that integrates hardware, software, and prototyping. The hardware components include a 32-bit ARC audio processor, digital I2S and S/PDIF interfaces, and an analog audio codec. The software components include a ready-to-use software environment that seamlessly pops into the main application, and a comprehensive library of software audio codecs that support the latest audio standards from Dolby, DTS and SRSLabs. The subsystem also includes virtual and FPGA-based prototypes to accelerate software development and validation of the entire system. The SoundWave Audio Subsystem gives designers a ready-to-use solution for configurable SoCs that can be easily integrated into SoCs.
3. How much work does this solution reduce for the designer?
A: This solution saves at least two years of work for design integration and verification. These workloads include: identifying application requirements, performing hardware/software functional partitioning, selecting and configuring IP from different vendors, IP integration and development of hardware/software architecture, host interface software development, functionality, integration and performance testing And the SoC design process.
4. How does the DesignWare Audio Subsystem help designers address the IP integration and software challenges they face today?
A: As more and more functions are integrated into a SoC, developing and maintaining the necessary functional modules is costly and time consuming, and these modules are complex and cannot be considered as differentiated technologies. By integrating multiple IP blocks and software into a pre-verified subsystem, Synopsys brings designers a configurable, ready-to-use audio solution in the SoC that enables them to quickly implement their SoC requirements. Audio features. This significantly reduces their SoC design and integration effort, reduces design risk, and enables them to focus on developing differentiated parts of their applications and speeding time-to-market.
5. What are the benefits of the DesignWare SoundWave audio subsystem to customers?
A: The SoundWave audio subsystem has the following advantages:
· Complete, integrated hardware and software solutions that enable "out of the box" audio capabilities that support the latest audio standards;
· Single-core and dual-core energy-efficient 32-bit ARC audio processors enable parallel support for multiple HD, multi-channel audio streams;
· Comprehensive software audio codec library including support for the latest audio standards such as Dolby Digital Plus, DTS-HD Master Audio and SRSLabs' TruSurround HD4;
· Digital audio interfaces such as S/PDIF and I2S provide multi-channel inputs and outputs;
· Analog audio codec provides high quality connectivity for line out input, microphone, speaker and headphones with a dynamic range of 96 dB;
· Virtual and FPGA-based prototyping accelerates software development and validation of the entire system;
· Complete software solutions are instantly available and seamlessly populated into the main application. This includes an integrated media stream framework with embedded decoder, encoder and audio post-processing functions, where audio post-processing features include volume control, equalization, surround balance and real-time operating system, and all software is connected to them. Also included is an audio plug-in based on industry-standard GStreamer multimedia software that enables developers to quickly integrate audio subsystem software into their main application software;
· An easy-to-use configuration tool that allows a complete audio subsystem to be configured in a matter of hours rather than a few weeks;
· Flexible buffer architecture eliminates the need for additional direct memory access (DMA) IP;
· SoC integration services are available to help implement and optimize subsystems throughout the chip environment.
6. What makes this IP product unique?
A: Synopsys is the only company that offers a complete solution for the audio IP subsystem. The subsystems include dedicated hardware, a complete integrated software environment, virtual and FPGA prototypes, and a configuration tool. Other solutions on the market are not complete subsystem solutions, requiring users to identify missing components, such as hardware and software, and then manually add them. Users also need to go through the entire time-consuming system debugging and verification process. This adds significant cost, time and risk to their customers.
The SoundWave Audio Subsystem is a complete, pre-integrated, proven solution that includes all the necessary audio functions (hardware and software) and saves at least two years of design integration and verification effort. time. Customers now have a single supplier that offers a complete audio solution.
7. How important is the software for the SoundWave audio subsystem?
A: Software is a differentiating factor. In general, companies developing SoCs spend more time on software than hardware, and this difference continues to grow as product complexity increases. By providing a complete audio subsystem with built-in and proven software, Synopsys enables customers to focus their resources on other, more critical factors in their design.
8. Can this subsystem be configured for the specific design requirements of the customer? Is the configuration predictable or necessary?
A: Because there is no one-size-fits-all audio design, we can enable our customers to fully configure the subsystem. The following can be configured by using Synopsys' coreAssembler tool:
· Number of digital interfaces (I2S and S/PDIF) and their parameters
· The number of interfaces connected to the analog IP and their parameters
· ARC audio processor configuration options (including cache size)
· Required software components (decoder, encoder and post-processing functions)
· Clock management options
· Reset management options
9. Is this audio IP subsystem suitable for standard SoC hardware/software integration processes?
A: Yes, by complying with industry interface standards such as AMBA AXI and AHB, and GStreamer software standards for Linux and Android, while complying with the specifications provided by Synopsys design and verification tools, we will help ensure compatibility with existing hardware and Convenient integration between software design processes.
10. What is the price of the SoundWave audio subsystem?
A: Synopsys' policy is not to disclose our pricing. This is due to the different needs of our IP customers' different business models, we will provide tailor-made quotations for each customer.
11. Do you have customers using the SoundWave audio subsystem?
A: We are currently negotiating with early customers, but due to confidentiality we cannot disclose any specific details at this time.
