LSI has introduced the Axxia Communication Processor range, which is designed for wireless infrastructure applications.

Featuring the LSI Virtual Pipeline message-passing technology, Axxia Communication Processor devices will provide users with fast, deterministic performance for demanding wireless applications, including video streaming, web browsing and high-quality digital voice, according to the company.

‘The Axxia Communication Processor range featuring the asymmetric multi-core architecture from LSI will enable networking equipment OEMs [original equipment manufacturers] to design 3G and 4G base stations, gateways and core and access routers that have the power, intelligence and built-in security to handle this growth,’ said Bob Wheeler, senior analyst for The Linley Group.

Axxia Communication Processor systems are capable of managing large volumes of wireless traffic with low latency and no load on the central processing unit (CPU) complex.

The first member of the Axxia Communication Processor range, the ACP3448 processor, features four PowerPC 476FP processor cores with a large 512KB L2 cache per core, 4Mb of system cache, integrated DDRIII memory controllers and a selection of intelligent offload engines, including packet classification, traffic management, security processing and deep-packet inspection.

The on-chip processing elements are tied together using the new LSI Virtual Pipeline technology.

According to Gene Scuteri, vice-president of the Networking Components Division at LSI, the Axxia range contains the first devices based on the LSI asymmetric multi-core architecture and featuring Virtual Pipeline technology.

‘The asymmetric multi-core architecture allows LSI to deliver scalable SoC [system-on-chip] solutions with common, reusable software across platforms,’ he said.

Virtual Pipeline technology uses deterministic modelling and distributed queue management to optimise inter-processor message routing, resulting in improved efficiency and less on-chip traffic congestion, delivering benefits such as wire-speed security processing with no CPU load.

The technology gives network operators the tools to manage traffic congestion in real time, improving the response time and the quality of service with minimal CPU utilisation.

Turnkey application development kit (ADK) modules, application programming interfaces (APIs) and software modules are provided to enable users to develop software for wireless applications.

‘Tier-1 mobile network equipment manufacturers are now developing systems based on the Axxia range that can cope with the immense demand being placed on wireless networks,’ said Scuteri.

The first members of the Axxia range, designed to deliver 20Gbps performance for today’s wireless infrastructure requirements, are available now.
