Cavium Networks Inc. has introduced a wireless processor with integrated control processing, networking processing and security capabilities. The CN52XX wireless processor is suitable for a wide range of wireless applications including 3G Transport, 4G Transport or Long Term Evolution (LTE)), wireless LAN aggregation, WiMAX base station and WiMAX Transport. It is the newest addition to the OCTEON Multicore MIPS64 processor family.

The Octeon CN52XX wireless processors provide a highly scalable and integrated Layer 2 to Layer 7 solution with hardware acceleration that supports both wireless and wired networking functions. The CN52XX wireless processors deliver over 1Gbit/s of WiMAX base station protocol performance, AAL2, 4Gbit/s+ of minimum packet routing, robust header compression, Kasumi for over-the-air encryption and IPsec for wired links.

The CN52XX family consists of six different software- and pin-compatible parts with 2 to 4 cnMIPS-plus cores, running at clock speeds from 500MHz up to 900MHz. All CN52XX wireless processors integrate 512KB of L2 cache, a 72-bit DDR2-800 memory controller, up to 4x Gigabit SGMII interfaces or one 10Gbit XAUI interface, two MII management interfaces and two PCIe controllers each with 2-lanes or one controller with 4-lanes.

In addition, the CN52XX wireless processors incorporate existing Octeon processor family hardware acceleration for packet processing, QoS, TCP and multicore acceleration. This high-level of integration and hardware acceleration provides three to five times the performance in wireless applications when compared to alternative solutions with the same price and power ranges, according to Cavium.

The CN52XX wireless processor is fully software compatible with the entire Octeon and Octeon Plus multicore MIPS64 processor family. The CN52XX wireless processor is supported by Cavium's software development kit with SMP Linux 2.6, GNU Toolchain, debugger tools, co-processor acceleration APIs, reference software and a comprehensive eco-system for a range of wired and wireless networking, storage and service provider applications.

Pricing starts at $49 in quantities of 10,000 for the Octeon CN52XX wireless processor family. Evaluation boards and general samples will be available in Q2 2008.
