Xelerated begins production of HX family of 100G NPUs

Carrier Ethernet ASSP-based chipset specialist Xelerated has begun volume production of its HX family of 100G network processors (NPU) for packet-OTN, mobile backhaul/PTN and Carrier Ethernet Switch-Routers. The HX family of NPUs has been selected in twenty systems, out of which the first will go into production later this year. Compared to legacy NPUs, the HX family reduces power consumption per processed gigabit of traffic by 67 percent. Designed for pizza box and line card slot capacities of 20-200 Gbps, the HX family integrates inherent wirespeed processing and advanced traffic management with deep packet buffering. In packet-OTN systems, the HX NPU enables Ethernet/MPLS services for 100 Gbps of traffic using a single chip. These line cards are designed for aggregation and transport, and support a range of interface types including GE, 10GE, 40GE, 100GE and OTU0-OTU4. In mobile backhaul, the HX family implements complete L2 and L3 switch-router applications. The HX family of NPUs provides a line-card-on-a-chip approach, including dataflow architecture featuring 448 PISC processor cores and 28 engine access points to connect to on-chip or off-chip table memory and hardware engines. HX family of NPUs also includes advanced traffic manager with hierarchical per-user, per-service scheduling and shaping and deep off-chip packet buffer implemented in DDR3 DRAM, embedded switching with advanced pre-classification for intelligent oversubscription. HX family of NPUs also includes internet-scale forwarding of IPv4 and IPv6 through memory interfaces to off-chip TCAM, SRAM and DDR3 DRAM and Synchronous Ethernet and support for one-step PTP IEEE-1588. The HX NPU family was first to demonstrate 100G wirespeed network processing last year and is now in-design for a new generation line cards and pizza boxes.
