Mercury Computer, Tundra Debut Serial RapidIO AdvancedTCA Platform

4/28/2004 - Mercury Computer Systems, Inc. (Nasdaq: MRCY - News) and Tundra Semiconductor Corporation (TSX: TUN -News) announced Ensemble, a serial RapidIO® Advanced Telecom Computing Architecture (AdvancedTCA®) development system. Demonstrated for the first time during the keynote address at the Motorola Smart Network Developers Forum (SNDF), the Ensemble platform leverages industry standards including the high-bandwidth, scalable serial RapidIO switch fabric, and AdvancedTCA, to enable telecom equipment manufacturers to start their next-generation infrastructure designs.

"Increased competition in the telecommunications market is forcing service providers to introduce more sophisticated and user-friendly services at an accelerated pace. The market wants a cost-effective and low-risk solution for the required underlying technology," said Mark Skalabrin, vice president and general manager, OEM Solutions at Mercury Computer Systems. "Mercury developed the Ensemble platform to put the power and functionality of serial RapidIO into the hands of the equipment providers. Ensemble will enable telecom equipment manufacturers to gain valuable application-specific insights into the capabilities of RapidIO as an embedded fabric architecture that will reduce integration costs and shorten time to market."

The Ensemble platform combines Mercury's serial RapidIO technology and system-level expertise with Tundra's parallel RapidIO Tsi500(TM) Multiport Switch, resulting in reduced integration costs, improved efficiency, and minimal risk for customers as they design and test their next-generation applications. Additionally, because Ensemble is standards-based, it is easily deployed and shortens time to market. Ensemble is an off-the-shelf, multipoint-to-multipoint (full-mesh) architecture. It is capable of supporting the running of up to 15 RapidIO endpoints, such as the Motorola PowerQUICC III processors, switched over RapidIO.

"Our customers want a standards-based prototyping platform where they can benchmark real applications. Ensemble features new technology in a form factor that enables OEMs to readily evaluate the performance and take their products to market," said Jim Roche, president and CEO of Tundra. "Ensemble demonstrates that RapidIO is the next-generation embedded switch fabric for communications applications."

About Ensemble
Ensemble's RapidIO embedded fabric is formed by five mesh-enabled carrier boards, each with onboard aggregate bandwidth of 100 Gbps. Each AdvancedTCA carrier board has three parallel interfaces and one serial interface brought to three mezzanine sites for processor XMCs or front-panel I/O. The mezzanine sites accept IEEE 1386.1 standard PMCs or XMC cards. (The pending VITA 42 standard addresses XMC cards with RapidIO communications.) A fully configured system can encompass 15 mezzanine modules per chassis and as many as 20 separate endpoints, enabling scalability to support application benchmarking tasks.

In addition to the built-in performance and flexibility of the hardware, Mercury makes available a Linux-based software suite for Ensemble to exploit RapidIO's rich in-band management features. It enables customers to monitor real-time performance, trap on certain events in the switch complex, and detect and mitigate the effects of errors. Ensemble exposes these features to customers, so that in the early deployment phases of RapidIO, customers can experiment and tune applications to the underlying performance characteristics of the network.

Ensemble will be in testing with beta customers in June, and is expected to be generally available in August 2004.
