NetLogic Microsystems Ships World’s First Knowledge-based Processor capable of achieving 1.2 Billion Decisions per Second

The NL8000 incorporates ground-breaking innovations and represents several industry firsts in knowledge-based processing technology to achieve a new performance milestone.

Mountain View, Calif. – April 23, 2007 – NetLogic Microsystems, Inc. [NASDAQ: NETL], the leader in the design and development of knowledge-based processors, today announced initial revenue shipments of the NL8000, its fourth generation knowledge-based processor, to its leading customer in support of multiple programs covering a range of advanced products.

The NL8000 knowledge-based processor features a number of major advances and industry firsts in knowledge-based processing. The NL8000 processor is the first in the industry capable of achieving 1.2 billion decisions per second (BDPS), which is more than double the packet processing performance of NetLogic Microsystems’ third generation solution, and incorporates advanced clock switching schemes to achieve an aggregate throughput of 40 gigabits per second. The NL8000 device also achieves new levels of parallel processing performance through a patented dual-core technology and a first-of-its-kind ability to parse decisions into 64 unique processing elements. This capability to execute multiple parallel decisions during a single core clock cycle combined with our highly pipelined synchronous cross-connect bussing scheme enables customers to deploy 100 Gbps ASIC, Switches, and Network Processors.

The NL8000 knowledge-based processor also supports more than half a million Quality-of-Service (QoS) or Access Control List (ACL) entries, which is twice the number of entries compared with any other device addressing the NL8000’s target market. This extends NetLogic Microsystems’ technology and market leadership in knowledge-based processing, and enables NetLogic Microsystems to optimally address the processing requirements of even the most feature rich networking systems.

First samples of the NL8000 were shipped in December of 2006 and these devices have undergone intensive customer system validation over the past four months. This testing points to flawless execution with first silicon, which will allow the company to move the NL8000 into volume production within the next several months, the fastest transition to date for the company in moving a new product from first silicon tape-out to volume production. This is an extraordinary achievement considering the myriad of new advances and difficult performance targets of this fourth generation product, and the design use of hundreds of millions of high-speed logic transistors.

“Through the exemplary work of our engineering teams, we are pleased to offer a new solution that can dramatically enrich the feature set and boost the throughput performance of advanced networking systems,” said James McDermott, director of marketing at NetLogic Microsystems. “We are excited to continue to be at the forefront of innovation and to extend our technology leadership in knowledge-based processing.”

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 quadruple-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’s superior processing performance uniquely addresses these requirements of next-generation networking equipment classification requirements.
