NetLogic Microsystems Inc. unveils the newest member of its XLP processor family, the XLP316 processor, that features a quad-core, 16-issue, 16-threaded, superscalar processor architecture at up to 2.0GHz with out-of-order execution and L3 cache designed for the most demanding control-plane processing requirements in communications, networking, storage and security applications.

Control-plane processing requirements in 3G/4G LTE mobile infrastructure are increasing due to the growth in signaling traffic from smartphones and tablets. Always-on mobile broadband applications that run on these devices make frequent connections to the network to check for updates to emails and social networking sites, as well as to perform other background processes. The accumulation of these frequent bursts of signaling traffic is placing an unprecedented burden on control-plane processing that requires new levels of processing horsepower while maximizing energy efficiency in next-generation mobile infrastructure equipment.

In addition, the industry migration to IPv6 networking, driven by the exhaustion of IPv4 addresses, is creating significantly higher control-plane processing requirements. Because IPv6 generates over 28 orders of magnitude more Internet addresses than its predecessor, this increases the burden on control-plane processing to manage and update the complex IPv6 databases.

NetLogic Microsystems' XLP316 processor is designed to address these control-plane performance requirements by combining powerful multicore processor architecture with a high-performance floating point unit and a low latency tri-level cache architecture. When compared to competing quad-core processors with dual-issue and single-threading per core, in-order execution and missing L3 cache, the XLP316 boasts up to 400 percent higher control-plane processing performance, which enables original equipment manufacturers (OEMs) to develop advanced, scalable systems for next-generation LTE and IPv6 networks.

The XLP316 processor integrates 16 NXCPUs which are cache and memory coherent for software applications to run in Symmetric Multi Processing (SMP) or Asymmetric Multi Processing (AMP) modes. The 16 NXCPUs are efficiently interconnected via NetLogic Microsystems' high-speed, low-latency Enhanced Fast Messaging Network to support billions of in-flight messages and packet descriptors between all on-chip elements. The XLP316 multicore processor offers a tri-level cache architecture with 4MB of L3 cache and over 6MB of fully coherent on-chip cache which delivers 40Tbps of extremely high-speed on-chip memory bandwidth. The XLP316 processor also incorporates one channel of 72bit DDR3 interconnect that yields over 100Gbps of off-chip memory bandwidth.

The multicore processor family is supported by a comprehensive software development kit (SDK) that contains reference and production-ready software components, which enables customers to accelerate time-to-market.

NetLogic Microsystems is now accepting orders for the XLP316 processors with standard lead times.
