Advanced Algorithmic Knowledge-based ProcessorsNetLogic Microsystems’ Sahasra™ family of algorithmic, knowledge-based processors is a single-chip, forwarding/LPM-optimized engine designed to provide the high route capacity for next generation switches and routers. These devices provide line-rate packet forwarding decisions at 40 Gbps and beyond. These algorithmic devices offer the ability to store 1.5 million IPv4 routes and search them at 40 Gbps with deterministic latency. SRAM-based technology allows for significantly reduced power consumption when compared to similar TCAM densities. With the entry compaction offered by the algorithmic technology, a single Sahasra device can replace 72Mb of standard TCAM in forwarding applications, at a fraction of the cost and power. Key applications for the Sahasra family of forwarding, knowledge-based processors include virtual router forwarding (VRF), virtual private networks (VPNs), as well as general, all layer switching and routing.
NETLite™ Processor FamilyNetLogic Microsystems’ NETLite™ processor family is specifically designed for cost-sensitive, high volume applications such as entry level switches, routers and access equipment. This family leverages circuit techniques developed and refined during the design of NetLogic Microsystems’ current market proven knowledge-based processor families, and greatly benefits from die size optimization, low power dissipation and redundant computing techniques. In addition, the NETLite processor’s simplified pipeline architecture allows for a lower cost of manufacture and lower cost system designs. These processors are ideal for entry-level systems that do not require the advanced parallel processing and deep pipelining performance of NetLogic Microsystems’ high-end knowledge-based processors. This product family is capable of processing speeds of up to 133 million decisions per second, and supports up to 512K IPv4 and up to 128K IPv6 routing entries. This significant increase in database capacity enables entry level networking products to support the deployment of an array of advanced IP network features including IPv6 routing, QoS, security and packet classification on converged networks for voice, video and data communications. To increase the data base capacity the devices can be cascaded without glue logic or performance degradation.
NPU-based Interface
Ayama™ ProcessorsNetLogic Microsystems’ Ayama™ products are a family of NETLite™ processors designed to provide classification in enterprise, metro, and wide-area networking platforms. These devices offer the ability to store up to 512K 36-bit IPv4 routes, and search rates of up to 266 million decisions per second. A SRAM port allows for glue-less interface to associated data, and a cascade port enables depth expansion for larger database sizes. The Ayama™ 10000A family of NETLite™ processors utilizes a high-bandwidth 72-bit DDR interface to connect to ASICs, FPGAs, and NPUs. The Ayama 20000 family of knowledge-based processors utilizes the industry-standard LA-1 interface to up to two NPU devices. An associated data manager efficiently organizes and accesses next-action data and a cascade port allows for depth expansion with the Ayama 10000A family of knowledge-based processors, or the Sahasra family of algorithmic knowledge-based processors. A typical cascade configuration includes 1.5M IPv4 routes and 256K ACL entries
