NetLogic Microsystems Now Sampling Second Generation Knowledge-Based Processor Family; NL6000 Processor Family Extends Company's Leadership Position in Processing Performance and Power Efficiency.

MOUNTAIN VIEW, Calif. -- NetLogic Microsystems, Inc. (Nasdaq:NETL), a leader in the design and development of knowledge-based processors, today announced sample availability of its second generation knowledge-based processor product family known as the NL6000. The NL6000 family is a series of ultra high-speed, low-power network performance enhancing processors designed for applications such as Edge, Core, Access, Metro and Enterprise switches, routers and access equipment.

"By introducing a second generation of knowledge-based processors, we are moving the available performance and power efficiency beyond the leadership capabilities of our first generation products allowing a greater level of intelligence to be added to the highest performance routing and switching equipment," said Jim McDermott, director of product marketing for NetLogic Microsystems. "The NL6512D-400 is now sampling at 400MHz operating frequency, which represents a 50 percent increase over the fastest products currently in volume production, and is further targeted to operate at speeds up to 500MHz. Using a new core processing technology, the NL6000 will deliver these enhanced performance levels while consuming less than half the power of the prior generation NL5000 family devices. We are very pleased to see the NL6000 family sampling to the market with first pass silicon success, which is a tribute to the skill and development efficiency of our R&D team."

The NL6000 family of knowledge-based processors is based on a new processing core design that utilizes innovative circuit techniques and architectural advancements to almost double the performance while reducing the power consumption by more than half over previous designs. Included in this new processor core is an intelligent active power management control that is used to selectively turn off unused processing elements on a cycle-by-cycle basis. In order to effectively deploy the available processing capability, the NL6000 family products also integrate an enhanced input/output (I/O) technology that supports data input rates up to 36 Gigabits per second.

Key to NetLogic Microsystems' knowledge-based processor design is the use of parallel processing and deep pipelining techniques, which allows the device to handle multiple tasks at higher throughput rates. Parallel processing enables multiple decisions to be made simultaneously for QoS, access control and voice/video packet forwarding, which significantly increases performance and allows IPv6 packet processing at wire-speed.

Similar to NetLogic Microsystems' NL5000 knowledge-based processors, the NL6000 product family is built on advanced CMOS logic, copper interconnect, low-power process. In conjunction with the NL6000's innovative architecture, the low power transistors maximize performance and yield while achieving lower power and higher reliability than can be attained with previous designs.

The NL5000 and NL6000 families of knowledge-based processors are footprint compatible, allowing existing designs to easily migrate to NL6000 knowledge-based processors. The NL6000 processors are available in small 25 x 25 mm footprint packages and have already achieved early success with sampling to tier one customers.
