Seamless Interfaces and Roadmap to Integrated Devices Speed Time to

Market

IDT (Integrated Device Technology, Inc.)(Nasdaq:IDTI), a leading communications IC provider, and Applied Micro Circuits Corp. (AMCC) (Nasdaq:AMCC), a leader in high-bandwidth silicon connectivity solutions empowering intelligent optical networks, today announced the formation of a partnership to seamlessly interface IDT's Internet protocol (IP) co-processors and AMCC's network processors in OC-12 to OC-192 line-rate applications such as edge routers and security products.

The joint solutions will streamline the development process to reduce development time and costs, enabling equipment designers to quickly bring next-generation network equipment to market. IDT will deliver integrated devices compliant with AMCC standards for next-generation network processor interfaces in the first half of CY02.

Through this relationship, IDT's IP co-processors will provide a glue-less interface to AMCC's nP3400, nP3404, nP7250 and nP7510 network processors, eliminating the need for programmable logic or an application-specific integrated circuit (ASIC) interface. The glue-less integration will enable the IP co-processor to seamlessly offload the compute-intensive searching functionality involved in packet classification and forwarding from the network processor, thus providing the network processor with more overhead to address applications like traffic management, security and accounting.

"AMCC recognizes IDT as a leader in packet-processing solutions, particularly in IP co-processing products, and is pleased to partner with IDT to provide complementary products for a complete solution," said Keith Morris, director of product management for AMCC's Switching and Network Processing Group. "We also value the fact that IDT offers our mutual customers stability and a strong history as a volume product provider."

"As a supplier of a wide range of components including integrated processors, IP co-processors, telecom products, FIFOs and clock management devices, IDT is solidly positioned in the packet-processing markets," said Rick Kepple, IDT's vice president of strategic marketing. "We are pleased that we can leverage our technology expertise and worldwide sales channel to partner with market leaders of complementary technology, like AMCC, to supply a best-of-breed system solution that meets the rigorous next-generation requirements in packet-processing applications."

To further augment the interaction between the companies' products, IDT and AMCC are working together on a development system utilizing IDT's IP co-processor evaluation board and AMCC's nP Workbench development system. IDT is also collaborating with AMCC to ensure software compatibility that will enable fast-time-to-design for customers.

IDT IP Co-Processors

IDT is the volume shipment leader of full-ternary IP co-processor devices. By integrating content addressable memory (CAM) technology with high-performance logic, IDT provides IP co-processing solutions to accelerate high-performance forwarding and deep packet classification, as well as policy-based applications. IDT's IP co-processor family is comprised of hardware-based parallel search engines that assist ASICs, field programmable gate arrays (FPGAs), network processor units (NPUs), and classification processors. IDT's IP co-processor products, coupled with an NPU or classifier, provide an order of magnitude system performance improvement over stand-alone NPU solutions.

AMCC Network Processors

AMCC's Switching and Network Processing Group (formerly MMC Networks) is the pioneer and market leader of network processors, enabling network and communications equipment vendors to rapidly develop scalable, feature-rich, cost-effective products. AMCC chip sets form the silicon heart of Layer 2 to Layer 7 WAN and LAN switches and routers, broadband, optical, web switching, subscriber management, and other communications platforms. AMCC's Total Network Processing Platforms include fully software-programmable, policy-enabled network processors; an open, extensible software architecture; high-capacity switching fabrics; and integrated traffic management engines -- all complemented by experienced and comprehensive system design and consulting services.
