Tensilica Processor Technology to Power Hughes Network Systems' Next Generation Spaceway Satellite Network

SANTA CLARA, Calif.--(BUSINESS WIRE)--May 29, 2001--Tensilica® Inc., the Santa Clara, California (USA) provider of configurable processor technology, today announced that Hughes Network Systems (HNS) has licensed the company's Xtensa(TM) technology. The multi-year, multi-million dollar deal is Tensilica's most significant since the company's inception.

According to Hughes Network Systems, the world's leading provider of Broadband Everywhere(TM) services and products for consumers and enterprises, Xtensa cores will be employed in various elements of Spaceway(TM), the next generation satellite-based broadband network that will provide very high bandwidth, two-way communications between customer (user) sites via geostationary satellites. The Spaceway North American network includes the initial development and deployment of three satellites, Network Operation Centers (NOCs), and multiple versions of satellite terminals providing bandwidth on demand for a variety of broadband and multimedia applications to enterprise and consumer sites.

``Spaceway is our highest priority program,'' said Dan Fraley, Hughes Networks Systems' senior-vice president of engineering, ``and its success is crucial to maintaining HNS's position as the worldwide leader in satellite-broadband technology. Spaceway's challenging requirements necessitated a search for cutting-edge technologies to achieve the project's aggressive performance goals.''

According to HNS, the system's architecture required a System on Chip (SOC) containing multiple unique processors, each precisely tuned to its assigned function. ``After an extremely thorough evaluation of processors from several industry-leading companies, it was clear to us that Tensilica's Xtensa provided the performance, time-to-market, and verification specifications that we required,'' Fraley concluded.

HNS will use numerous uniquely configured Xtensa processors in their SOCs. These will provide all of the processing requirements including high speed real-time data stream management plus running a leading RTOS on an Xtensa core configured as a high-end control processor.

Chris Rowen, Tensilica's president and CEO, said, ``This design win is truly significant for the company. Our technology was chosen over that offered by a field of older, larger, but well-qualified processor suppliers. I think it clearly confirms that the configurable processor approach for high-volume embedded systems is real and has become a compelling option for tomorrow's electronic products whether they are hand-held wireless devices, PDAs, or digital broadband satellite systems.''
