LSI Introduces ARM-based Axxia 5500 Processors for 4G Base Stations

LSI introduced its ARM-based family of Axxia 5500 processors designed for multi-radio LTE base stations, cell site routers, gateways and mobile backhaul equipment.

The new processors combine up to 16 ARM Cortex-A15 cores with LSI specialized networking accelerators to optimize performance and power efficiency.  On-chip network accelerators deliver up to 50 Gbps packet processing, 20 Gbps security processing and 160 Gbps of Ethernet switching via 16 10G Ethernet interfaces. LSI plans to offer several versions with different core counts and throughput capabilities.  The chip design leverages ARM’s CoreLink CCN-504 low-latency interconnect in 28nm process technology.

LSI said its combination of networking expertise, specialized 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.

“The combination of ARM’s leading coherent interconnect, energy-efficient multicore processor technology and advanced physical IP in the LSI Axxia 5500 series delivers significant gains in performance density. This will enable highly efficient systems with new levels of software flexibility and scalability for heterogeneous networks,” said Ian Ferguson, vice president of Segment Marketing, ARM. “LSI and ARM enjoy a strong relationship, and we are working to meet the needs of customers who are focusing on building next-generation network infrastructure.”
