LSI Corporation has rolled out the ACP3423 communication processor that is suitable for devices such as multi-radio base stations and wireless backhaul. The Axxia communication processor family enables OEMs to deliver deterministic performance in wireless applications such as video streaming, web browsing and high-quality digital voice.
The communication processor is built using the company's asymmetric multicore architecture. It supports synchronous Ethernet, which is critical for frequency synchronisation for base-station and cell-site equipment deployed in all-IP and Ethernet networks. The communication processor supports IEEE1588v2 timing-over-packet timing synchronisation.
The communication processor is pin and software compatible with the other Axxia processors and is available in a pin-count package that minimises board space. It features two PowerPC 476FP processor cores running up to 1.6GHz and a wide array of intelligent offload engines, including packet classification, traffic management, security processing and deep packet inspection. The asymmetric multicore architecture allows processing of huge volumes of wireless traffic through the offload engines, enabling low-latency, fast-path processing with no load on the CPU complex. The on-chip processing elements are tied together using the company's virtual pipeline technology. The communication processor includes one XSBI attachment unit interface and eight serial gigabit media independent interface ports as well as peripheral component interconnect express and serial rapidIO interfaces.
