Synopsys and Alango Deliver Voice Communication Package for DesignWare ARC Audio Processors

Synopsys, a provider of software, IP, and services used to accelerate innovation in chips and electronic systems, and Alango Technologies, a developer and licensor of front-end voice enhancement technologies, today announced the availability of Alango's Voice Communication Package (VCP) for Synopsys' DesignWare ARCAS211SFX and AS221BD audio processors.

Alango's VCP, a universal software package of digital signal processing (DSP) technologies for voice applications, enables high-quality, full duplex, noise-free communication in noisy environments, such as cars and industrial settings. By integrating advanced signal processing software for voice applications with single- and dual-core ARC audio processors, Synopsys and Alango are providing designers of embedded systems with a pre-verified hardware and software solution that enhances voice communications while reducing design risk and time to market.

"High-quality voice processing is a requirement in the fast-growing communications markets, particularly in advanced mobile phones, tablets, laptops, and VoIP voice terminals often used in very noisy environments," said Alexander Goldin, CEO of Alango Technologies, in a statement. "Our Voice Communication Package improves the quality and clarity of voice transmissions on ARC audio processors. Our mutual customers are already taking advantage of the configurability and scalability of the integrated Alango-Synopsys solution."

VCP offers noise suppression, multiband frequency equalizers, dynamic range compressors, noise gates, and automatic gain control, all of which can be enabled and disabled within the software depending on the design's functionality and available DSP resources. ARC Audio Processors use the 16-/32-bit DesignWare ARCompact Instruction Set Architecture that provides reduced instruction set computer and full DSP capabilities in a unified architecture. The processors' extendable instruction set enables designers to create highly differentiated designs for a broad range of embedded applications, such as mobile phones, hands-free car kits, Bluetooth headsets, industrial intercoms, and other types of voice terminals.

"More than one billion chips ship annually with embedded DesignWare ARC processors, and the Alango VCP adds welcome capabilities to the growing ARC ecosystem," said John Koeter, vice president of marketing for IP and systems at Synopsys, in a statement. "Alango is a valued member of the ARC Access Program, and our combined audio processing solution demonstrates how close collaboration can address the latest challenges in demanding applications such as voice processing. By working with Alango, we make it easier for system-on-a-chip designers to integrate proven, high-quality audio functionality into their ARC-based SoCs, allowing them to focus on their core competencies."
