Octasic Inc has announced its next generation multi-core gateway DSP platform for voice, video and data over IP applications. Vocallo combines ultimate flexibility, with pristine voice and video quality, to deliver the most comprehensive solution for current and future media gateways, says the company.

Octasia claims that the Vocallo expandable media gateway solution is the first DSP platform of its kind to enable a new flexible business model for OEMs designing media gateways. This business model enables an OEM to design a cost-reduced gateway to handle today's Voice over IP needs with licensable performance to accommodate future applications. This allows OEMs to defer the costs of additional performance capacity until they deliver and charge for an application that requires it.

"Because requirements are constantly changing, there is a need for greater flexibility and expandability in media processing devices. Vocallo is the only solution today that allows OEMs to pick their features, add-in their own software and upgrade," said Frederic Bourget, director of product management at Octasic."Vocallo is powerful and flexible. It is a comprehensive solution for current and future applications."

Vocallo is based on Opus, Octasic's DSP core architecture, which offers high performance-to-power ratio with a traditional programming model. In high density applications, Opus is the most efficient DSP core processor by two-fold. In addition, Opus provides a rich instruction set that goes beyond DSP functions allowing for expandability into new applications.

One of the strengths of the Opus architecture is that it maintains a traditional programming model preserving customers' investment in applications and skill set. The ability to achieve such low power enables developers to leverage a multi-core DSP architecture without re-writing code. The Opus kernel and Integrated Development Environment (IDE) provide the tools necessary to quickly develop, test, and debug software for this high-performance DSP platform in a predictable fashion.

"Through its asynchronous design, Opus provides 3 times more performance per watt than current DSP architectures on the market today," said Doug Morrissey, Octasic CTO. "While the DSP core construction is clock-less, to the programmer it presents a traditional processing model. This is important to allow today's DSP programmers to take full advantage of its capabilities without having to be retrained to re-write and re-partition existing applications."

With its flexible hardware and software platform, Vocallo allows media gateway developers to match an offering to their specific requirements. The features and benefits of the Vocallo DSP can then be scaled to create a wide range of cost-effective products from a single design. As an added benefit, Vocallo allows designers to add their own software to the Vocallo framework to further differentiate their products.

"As VoIP adoption grows, service providers will continue to rely on media gateways," said Jon Arnold, principal of independent analyst consultancy, J Arnold & Associates. "Their needs will become increasingly complex, and Vocallo provides maximum flexibility to quickly adjust to changing market conditions."

Vocallo's Echo Cancellation and Voice Quality Enhancement (VQE) features use Octasic's carrier-approved algorithms. To maintain pristine voice quality in the latest standards, Vocallo is built on a packet-based software architecture designed from the ground-up to support wideband voice traffic and process media connections with minimum latency.

Forty million voice lines in networks worldwide rely on Octasic's carrier-recognised solutions. Building on this rich history, Vocallo supports emerging network architectures and applications, such as IMS and Fixed Mobile Convergence (FMC). In addition, Vocallo provides support for robust real-time video transcoding, transrating, and conferencing.

"Our experience in designing high density voice solutions for carrier equipment OEMs over the last ten years has led us to develop the Opus DSP core," said Michel Laurence, Octasic's president and CEO."Through its use in Vocallo and follow-on products, Octasic is providing processing platforms with new models of cost and performance allowing our customers to be more flexible and more competitive."
