Cavium Inc. released its base station-on-a-chip small cell family, which can be used for LTE and 3G cell base stations. The newly released chips, the OCTEON Fusion family, work with FusionStack software. It has multiple SoCs that can make a small cell work from 32 users and more towards a dual 20MHz carrier. OCTEON Fusion processors operate together with its MIPS64-based multicore architecture and purpose-built baseband DSP cores, extensive LTE/3G hardware accelerators and digital front-end (DFE) functionality, slashing the BOM cost and power envelope of small cell base stations.

The OCTEON Fusion processors combine OCTEON's proven and scalable L2-L7 multicore technology, already adopted in multiple tier-1 macro wireless equipment, along with purpose-built, highly programmable baseband DSP cores and extensive 3G/4G hardware accelerators along with digital front-end (DFE) functionality into a single chip. Combining 2x to 6x 64 bit cnMIPS cores, operating at up to 2GHz, with up to 8x highly optimized baseband DSP's, operating at up to 1GHz, and several carefully designed hardware accelerator blocks that interact through interconnects. This enables deterministic and low-latency data processing between protocol layers. The OCTEON Fusion family consists of two software compatible product lines: CNF71XX, CNF72XX, delivering industry leading performance and low power to enable small cell base stations supporting from 32 to 300+ users on both LTE and 3G platforms.

OCTEON Fusion includes FusionStack, a comprehensive software suite that is ready to be deployed in a Tier 1 LTE network, as a result of thorough interoperability radio conformance testing with multiple user equipment. PHY (L1) layer software includes complete user-plane and control plane components for FDD-LTE, TDD-LTE and 3G, along with protocol processing libraries that take advantage of the built-in hardware acceleration. The comprehensive deployment ready suite includes Layer 2 /3 libraries, network side control and timing synchronization, along with diagnostic tools.

"TEM's require small cell solutions with unprecedented levels of scalability, performance, security and manageability with the ability to offer differentiating capabilities such as QoS, interference mitigation and Self-Optimizing Networks (SON). We are delighted that our OCTEON Fusion family is able to provide industry-leading processing power to enable wireless TEM's to implement sophisticated macro class capabilities in a very compact and low cost footprint", said Syed Ali, president and CEO of Cavium. "Cavium has already built a strong position in the wireless infrastructure market by establishing an excellent foothold in 3G/4G macro BTS/Core network and the innovative OCTEON Fusion product line will enable us to further expand our market position in one of the highest growth areas of the infrastructure market."

First samples of CNF71XX and the FusionStack software will be made available in 1Q12; the CNF72XX will be on offer subsequently.
