LSI Corp. has announced a family of communication processors aimed to accelerate performance and increase power efficiency for multi-radio base stations and 4G/LTE-capable wireless networks. The LSI Axxia 5500 product line claims to be the first to combine 16 ARM cores with LSI specialised networking accelerators to optimise performance and power efficiency.

The Axxia 5500 product family allows networking service providers enhanced intelligent wireless capabilities through base stations, cell site routers, gateways and mobile backhaul equipment. The devices are said to feature reliable, deterministic performance to contend with the massive data deluge driven by smartphones, tablets and cloud-based services, increased power efficiency that enables OEMs to widely deploy high-performance macro and small cell base station solutions, and lower capital expenditure costs and optimised system design due to integration of networking acceleration functions including up to 50Gb/s packet processing, 20Gb/s security processing and 160Gb/s of Ethernet switching via 16 10Gb Ethernet interfaces.

The Axxia 5500 product family will include a range of communication processors with different core counts and throughput capabilities claim to be the first in the industry to deliver 16 ARM Cortex-A15 cores using ARM's CoreLink CCN-504 low-latency interconnect in 28nm process technology. The combination of LSI's networking expertise, specialised acceleration engines and Virtual Pipeline technology with ARM's power-efficient processors and interconnect IP delivers communication processors that are uniquely suited for building intelligent, heterogeneous networks.

LSI also said it offers a comprehensive tool suite and production-quality wireless application enablement software. LSI's optimised, high-performance layer two through four software packages provide a complete wireless transport solution for networking OEMs, eliminating the need to invest in data plane software development. The LSI Axxia platform is geared for OEMs to meet accelerated time-to-market goals and efficiently leverage their development resources for emerging heterogeneous network architectures.
