Greater Demand, Greater Opportunity
The increasingly complex requirements placed on the Internet, intranets and
extranets have created an insatiable demand for higher speed and greater capacity in
communications networks. The evolution of converging communications networks
requires higher levels of security and increasingly sophisticated network
intelligence. These network demands, and the user expectations that drive them,
have created a global need for well-managed and ever-increasing bandwidth.
Tundra helps meet those demands by creating underlying technology that enables
the accelerated flow of voice, data, and video information over communications
networks. Tundra products can be found in a broad range of applications, including
telecommunications, data communications, wireless communications, industrial
automation, and avionics. Communications infrastructure vendors rely on Tundra
for off-the-shelf, standards-based, easy-to-deploy and highly scalable System
Interconnect products.

Corporate Profile
Tundra System Interconnect
Tundra is
System Interconnect.
Tundra uses the term System Interconnect to refer to
the technology used to connect all the components and sub-systems in almost any
embedded system. This concept applies to the interfacing of functional elements
(CPU, memory, I/O complexes, etc.) within a single-board system, and the
interfacing of multiple boards in a larger system.
System Interconnect is a vital enabling technology for the networked world. The
convergence of voice, video, and data traffic, the need for more secure
communications, and the exploding demand for high-speed network access are
putting communications infrastructure vendors under intense pressure to provide
faster, well-managed bandwidth that also integrates smoothly with existing
technology. Tundra System Interconnect helps these vendors address their customer
needs. It enables them to build standards-based network equipment that can scale to
multi-gigahertz speeds and also integrate with existing infrastructure.
Partnerships
Fundamental to the success of Tundra is its partnerships with leading
manufacturers, including Motorola, Compaq and Texas Instruments. As a result of
these alliances, Tundra devices greatly influence the design of customers’
architectures. Customers are changing their designs to incorporate Tundra products.
This highlights the commitment Tundra holds to be a significant part of its
customers’ success.
The Tundra design philosophy is one in which a number of strategic customers are
invited to participate in the definition, design, test, and early silicon supply phases
of product development. Close working relationships with customers and clear
product roadmaps ensure that Tundra can anticipate and meet the future directions
and needs of communications systems designers and manufacturers.
