NetLogic Microsystems Introduces the World's First "Hybrid" Knowledge-based Processor with a Revolutionary Convergence Architecture

NetLogic Microsystems' fifth-generation knowledge-based processor family is the first-of-its-kind "hybrid" architecture that features the convergence of high-performance knowledge-based processing and superior low-power efficiency of algorithmic Sahasra™ technology

Mountain View, Calif. – Jan. 28, 2008 – 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 NL9000 knowledge-based processor as part of the launch of its fifth-generation knowledge-based processor family. The NL9000 processor is the industry's first fully-programmable "hybrid" knowledge-based processor that features the convergence of high-performance, massively parallel knowledge-based processing with the superior low-power efficiency and flexibility of algorithmic Sahasra™ technology to dramatically reduce power consumption while delivering best-in-class performance and functionality for next-generation IPTV and advanced mobile wireless networks.

The rapid proliferation of advanced mobile devices such as video phones, portable media players, mobile gaming devices and Internet Protocol (IP)-enabled global positioning systems (GPS) has accelerated the global industry migration from IPv4 to IPv6 networks. This transition is driving the need for knowledge-based processors with significantly higher performance, higher interface (I/O) bandwidth, enhanced flexibility, expanded set of new features and dramatically lower power consumption.

NetLogic Microsystems' NL9000 knowledge-based processor is the first-of-its-kind to offer an advanced "hybrid" architecture that is required to deliver the performance, features and flexibility for IPv6 systems while achieving power savings of up to 5X compared to non-hybrid solutions. This represents an important milestone and innovation for the industry as original equipment manufacturers (OEMs) strive to meet stringent low-power requirements for next-generation Advanced Telecommunications Computing Architecture (ATCA) and high-density datacenter systems.

"Enabling a hybrid architecture presents a viable option in addressing the challenge of delivering IPv6 processing capabilities at 64Gbps line rate while meeting the rigorous power and cost requirements of next-generation ATCA systems,î said Aileen A. Arcilla, senior analyst at IDC.

The NL9000 processor features a number of industry firsts and ground-breaking innovations that differentiate the NL9000 processor from previous generations of knowledge-based processors in terms of flexibility, performance, functionality and power. The NL9000 processor incorporates:

• Advanced Sahasra Algorithmic Engines (SAEs), which employ complex algorithms to provide customers with the ability to dramatically lower the power of search processing while expanding the effective processing power. The SAEs, which are the result of over seven years of intensive R&D development, are tightly coupled with the knowledge-based processing engines in the "hybrid" NL9000 processor to enable customers to optimally configure the NL9000 processor for the specific application.
  
  
• Intelligent Load Balancing Engine (ILBE), which is the first-of-its-kind engine with embedded intelligence to allocate multiple tasks and communicate among all 64 knowledge-based processing engines on chip, as well as to enable customers to perform iterative or nested search processing on all incoming traffic. This significantly enhances the processing efficiency of next-generation systems.
  
  
• Range Encoding Engine (REE), which employs advanced one-hot and fence encoding algorithms to implement range encoding that allows customers to effectively double the efficiency of performing port range inspection.
  
  
• Fifth-generation I/O design, which delivers 64Gbps of raw chip-to-chip interconnect bandwidth, which is 60% greater than previous generations of knowledge-based processors. When coupled with the ILBE, customers can achieve up to 100Gbps of effective bandwidth, allowing the NL9000 processor to support the most performance-demanding switching and routing applications currently in design.

"The revolutionary hybrid architecture of our fifth-generation knowledge-based processors offer very compelling benefits to our customers, and is clearly setting us apart from the competition," said Chris O'Reilly, vice president of marketing at NetLogic Microsystems. "We're excited to continue to be at the forefront of technology innovation and we're glad to see strong customer interest in our NL9000 product family."

The NL9000 knowledge-based processor is one of the most complex logic products manufactured in the advanced 55nm technology node of TSMC. The use of this advanced silicon manufacturing technology further enhances the performance and lowers the power of the NL9000, while providing the most competitive cost structure. The NL9000 is currently sampling to customers.
