NetLogic Microsystems Extends Its Worldwide Leadership in Fourth-Generation Knowledge-based Processors with the Introduction of the NL8256 Processor

With twice the breadth of fourth-generation products, NetLogic Microsystems has emerged as the worldwide leader in Gen-4 knowledge-based processors, and expects to achieve over 75% market share during the fourth quarter of 2007

Mountain View, Calif. – Dec. 10, 2007 – NetLogic Microsystems, Inc. [NASDAQ: NETL], the leader in the design and development of knowledge-based processors and high-speed integrated circuits, today announced the introduction of the NL8256 knowledge-based processor, which is targeted at mainstream applications and is the second device in its fourth-generation processor family.  This positions NetLogic Microsystems with twice the breadth of Gen-4 products relative to other suppliers with similar products.  Both the previously announced NL8512 and the NL8256 knowledge-based processors are currently shipping in volume production.

In order to support the increased complexity and higher bandwidths of network traffic, as well as the migration to IPv6, the industry is quickly transitioning to the fourth generation of knowledge-based processors.  NetLogic Microsystems’ advanced fourth generation processors lead the industry in performance, breadth and availability.  The solutions from NetLogic Microsystems are capable of achieving an industry leading 1.2 billion decisions per second (BDPS), and incorporates advanced clock switching schemes to achieve an aggregate throughput of 40 gigabits per second.  The NL8256 and previously announced NL8512 processors also achieve new levels of parallel processing performance through a patented dual-core technology and a first-of-its-kind ability to parse decisions into up to 64 unique processing elements.  This capability to execute multiple parallel decisions during a single core clock cycle, combined with NetLogic Microsystems’ highly pipelined synchronous cross-connect bussing scheme, enables customers to deploy 100 Gbps ASIC, Switches, and Network Processors. 

By integrating these advanced capabilities with a unique ultra-low power technology, NetLogic Microsystems has emerged as the worldwide leader in fourth-generation knowledge-based processors.  NetLogic Microsystems’ NL8000 family of fourth-generation knowledge-based processors has already gained broad adoption across a number of quad-play switch and router applications, receiving multiple design-wins in mainstream switching, core routing and service provider edge routing, and is expected to achieve over 75% in overall market share of the fourth generation market during the fourth quarter of 2007, as measured by both unit shipments and revenue.  As a result of higher performance capability, a broader product portfolio, and lower power consumption, this market leadership position in the Gen-4 architecture is expected to continue into 2008.

“We are extremely pleased about the tremendous success of our NL8000 family of fourth-generation knowledge-based processors and the continued expansion of the product family since it was launched earlier this year,” said Chris O’Reilly, vice president of marketing at NetLogic Microsystems.  “Our advanced innovation and history of first silicon successes have allowed us to accelerate the time from development to first revenue shipment.”

Original equipment manufacturers are increasingly looking to accelerate packet classification and forwarding in their systems as converged and multi-service unified IP networks evolve to provide quad-play services (i.e., the convergence of voice, video, data and wireless mobility) to end customers and as the next-generation networks migrate from IPv4 to complex IPv6 addressing.  The NL8000 processor family’s superior processing performance uniquely addresses these requirements of next-generation networking equipment classification requirements.

The NL8256 knowledge-based processor is currently shipping into the mainstream Gen-4 market, and represents the fifth consecutive first silicon success for NetLogic Microsystems.
