QorIQ LS2 Processor Family
QorIQ LS2085A Reference
Design Board
1U form-factor tool for evaluation and design of value-added
networking applications
Freescale’s QorIQ LS2085A processor is designed to enable network intelligence and capitalize
on the emerging trends of networking virtualization. The processor goes beyond the traditional
multicore approach, where performance is directly proportional to the number of cores
instantiated. Instead, the LS2085A processor adds an intelligent software-aware packet processor,
a versatile Layer 2 switch and a management complex that simplifies programming and that
delivers unprecedented efficiency and new virtualized networks.
The features and capabilities of the QorIQ LS2085A processor enable designs in enterprise SDN
switching and routing, cloud data center switching and wireless cell site routing. With up to eight
64-bit ARM® cores, the processor also enables many control-based applications like control plane
functions for branch routers, chassis switches, firewalls and WAN optimization controllers.
The QorIQ LS2085A reference design board (LS2085A RDB) provides a comprehensive platform
that enables design and evaluation of the product in all its instantiations: with options for
configuring an internal 8-port, L2 switch and the powerful and autonomous 40 Gbps advanced
packet processor.
