Synopsys, Inc. announced that DSP Group, Inc. selected SynopsysDesignWare® ARC® EM5D Processor IP for its high-efficiency control and signal processing capabilities to enable development of its DBMC2-TWS advanced adaptive processing audio codec for true wireless stereo (TWS) headsets. To dynamically configure settings and filter parameters on-the-fly, the DBMC2-TWS integrates an ARC EM5D processor, abundant internal memory and numerous digital interfaces. The processing capabilities of the ARC EM5D enable the deployment of advanced sound processing features, such as adaptive active noise cancellation (ANC), user ear placement characterization, and smart ambient awareness control. This allows the headset to autonomously respond to changes in product fit or the ambient sound conditions. DSP Group also leveraged the DesignWare ARC MetaWare Development Toolkit to ease digital signal processing (DSP) software development for its audio and voice processing SoC. The DSP-enhanced ARC EM processor family, which includes the EM5D, EM7D, EM9D, and EM11D processors, implements a scalable pipeline that offers an optimal balance of performance, power consumption and size for a range of control and DSP applications. Like all ARC processors, the DSP-enhanced EM processors are highly configurable so that each instance can be tailored to achieve the optimum balance of DSP and RISC performance. ARC Processor EXtension (APEX) technology offers designers the ability to create user-defined instructions, enabling the integration of custom hardware accelerators that improve application-specific performance while reducing power consumption and memory footprint. The DSP-enhanced ARC EM processors are supported by the DesignWare ARC MetaWare Development Toolkit, a complete suite of tools for developing, debugging and optimizing software targeted for ARC processors, which includes an enhanced C/C++ compiler supporting the 150+DSP instructions available for efficient algorithm development.
