NetLogic Microsystems Announces Production Shipments of the Industry’s First Knowledge-Based Processor Capable of Achieving 1.5 Billion Decisions Per Second

NetLogic Microsystems, Inc. (NASDAQ:NETL), the leader in the design and development of knowledge-based processors and high-speed integrated circuits, today announced production shipments of its NL91024XT knowledge-based processor, which is capable of achieving 1.5 billion decisions per second (BDPS) and is optimized for next-generation 100Gbps systems. As the latest member of NetLogic Microsystems' fifth-generation knowledge-based processor family, the NL91024XT processor is a 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(TM) technology to dramatically reduce power consumption while delivering best-in-class performance and functionality for next-generation IPTV and advanced mobile wireless networks.

NetLogic Microsystems' NL91024XT knowledge-based processor incorporates a new high-speed I/O design which delivers 100Gbps of raw chip-to-chip interconnect bandwidth, representing an improvement of more than 2x over competitive solutions. When coupled with the Intelligent Load Balancing Engine (ILBE), customers can achieve more than 150Gbps of effective bandwidth, allowing the NL91024XT processor to support the most performance-demanding switching and routing applications currently in design. This level of performance is necessary as architects develop system-level solutions capable of handling aggregate traffic rates of 100Gbps while simultaneously handling the high-levels of services and reliability required by the convergence of video, voice, data, and mobility, the emergence of Internet Protocol Television (IPTV), and peer-to-peer (P2P) communications.

Developed on TSMC's advanced 55nm process node, the NL91024XT processor integrates 128 high-performance knowledge-based processing engines. In addition, the NL91024XT processor features an enhanced ILBE to efficiently allocate multiple tasks and communicate among all the 128 knowledge-based processing engines. The knowledge-based processing engines and ILBE are tightly coupled with integrated advanced Sahasra Algorithmic Engines (SAEs) to dramatically lower the power consumption of search processing in the NL91024XT "hybrid" knowledge-based processor.

Through design improvements and process enhancements, the NL91024XT significantly increases the performance of each of the 128 engines as well as the ILBE and SAEs, as compared to the standard NL91024 device. The result is the breakthrough performance of 1.5 billion ACL and QoS decisions per second, 25% faster than any previous NetLogic Microsystems device and 50% faster than any competitive device, all at very low power thanks to the advanced Sahasra algorithmic technology.

All members of the NL9000 "hybrid" knowledge-based processor family also integrate an innovative Range Encoding Engine (REE). The REE 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.

"We're pleased to announce production shipments of the industry's first knowledge-based processor capable of achieving 1.5 billion decisions per second," said Chris O'Reilly, vice president of marketing at NetLogic Microsystems. "As virtually all of our key customers are rapidly moving to 40Gbps and 100Gbps dataplane designs, our clear technology leadership with the NL91024XT processor is enabling us to provide the most advanced solution for an important part of wirespeed processing in the most demanding next-generation designs for enterprise networking, cable, wireline and wireless infrastructure."

The NL91024XT knowledge-based processor is available now in production quantities and will ship this year to multiple Tier One OEMs for use in advanced next generation switch and router products for triple-play and quad-play applications in networking, wireline and wireless communications infrastructure.
