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

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.
