NetLogic Microsystems Inc. announces the release of its XLP864 multicore processor, a multicore communications processor featuring 64 NXCPUs. The XLP864 processor is the latest member of NetLogic Microsystems' XLP multicore, multithreaded processor family.

NetLogic's XLP864 multicore, multithreaded processor is optimized to deliver 80Gbps throughput and 120 Mpps of intelligent application performance for next-generation 3G/4G mobile wireless infrastructure, metro Ethernet, security, storage, enterprise, edge, and core infrastructure network applications.

NetLogic's XLP processor family claims to be the only embedded communications processor that features quad-issue, quad-threaded and superscalar out-of-order execution capabilities operating at up to 2.0GHz. The XLP cores are quad-threaded to minimize application bottlenecks due to memory latency, thereby improving performance for network data plane processing applications. Furthermore, the NXCPUs are equipped with a tri-level cache architecture with over 25MB of coherent on-chip cache which delivers 40 Terabit/sec of extremely high-speed on-chip memory bandwidth.

"The powerful XLP cores are well suited to a variety of performance-intensive applications," says Linley Gwennap, principal analyst of The Linley Group. "This design is already proven in the XLP832, which has been sampling to customers for more than six months. Since then, NetLogic has quickly completed the XLP864 design."

The XLP864 features NetLogic's high-speed, low-latency Enhanced Fast Messaging Network to enable efficient, high-bandwidth communication among the 64 NXCPUs and to support billions of in-flight messages and packet descriptors between all on-chip elements. To complement the 64 NXCPUs, the XLP864 processor offers over 80 fully autonomous processing engines that provide independent and complete offload of certain network functions from the NXCPUs, including:

???80Gbps fully autonomous Security Acceleration Engine supporting networking, wireless, and storage encryption/decryption/authentication protocols
???80Gbps Network Acceleration Engines for Ingress/Egress Packet Parsing and Management
???256Gbps RAID-5/RAID-6 Acceleration
???20Gbps Compression/Decompression
???Packet Ordering
???Storage De-Duplication Acceleration
???TCP Segmentation Offload
???IEEE 1588 Hardware Time Stamping

The XLP864 also integrates various high-speed networking interfaces, including Interlaken, XAUI, SGMII, PCI-Express, USB2.0, and NetLogic Microsystems' high-bandwidth Inter-chip Coherency Interface (ICI) that provides seamless chip-to-chip cache and memory coherency with full software transparency. XLP864 is manufactured in Taiwan Semiconductor Manufacturing Company's advanced 40nm process technology, enabling higher clock speeds, a lower power profile, and improved manufacturability compared to legacy 65nm process technologies.

NetLogic's multicore processor family is supported by a comprehensive software development kit that contains reference and production-ready software components, which enables customers to accelerate time-to-market for next-generation high-end equipment.
