Communication semiconductor solution provider Broadcom Corp. has announced that the sampling of its NLA12000 Series has begun. In addition to being suitable for data centres, 3G/4G mobile infrastructure and enterprise environments, the company claims that these processors are the industry's first 28nm heterogeneous knowledge-based processors (KBPs), could deliver up to 24 times greater performance than competitors.

Continued exponential growth in hosted services, coupled with emerging trends such as Software Defined Networking (SDN) and Open Flow, is driving the demand for increased classification, forwarding and security processing throughout the network. In addition, the industry's migration from IPv4 to IPv6 to accommodate the growing number of connected mobile devices is resulting in 4x larger knowledge databases for Layers 2-4 processing. Combined, these factors require knowledge-based processors with significantly higher performance, larger knowledge databases and lower power profiles.

The NLA12000 Series KBPs are the industry's first to integrate an eighth generation massively parallel knowledge-based processing technology with innovative low-power NetRoute algorithmic search technology in a heterogeneous manner, delivering the highest deterministic performance and low latency independent of database or signature complexity, with support for up to 2 million IPv6 routes.

In addition to delivering the highest performance, the combination of Broadcom's innovative NetRoute technology with the advanced 28nm process node enables the NLA12000 Series KBPs to achieve the industry's lowest power footprint for IPv4 and IPv6 searches.

Key Features

* 2.4 billion decisions per second (BDPS) to address growing line rates for IPv4 and IPv6 packets

* High-speed serial links for enhanced communication from KBP to system packet processors (includes 12.5 Gbit/s SerDes for 300 Gbit/s aggregate bandwidth)

* Dual-port mode for off-the shelf network processors, FPGAs and customer ASICs

* Improved search flexibility with Context Buffers and Key Processing Unit (KPU)

* Range Encoding Engine (REE) delivers efficient database compaction for access control lists

* Support for on-chip associated data for search tables to enable lowest system latency

Broadcom's 28nm heterogeneous KBPs are currently sampling with production volumes slated for 1H 2013.
