The QorIQ LS1 family is built on Layerscape architecture, the industry's first software-aware, core-agnostic networking architecture to offer unprecedented efficiency and scale. Freescale LS102xA is a set of SoCs combines two ARM Cortex-A7 cores that have been optimized for high reliability and pack the highest level of integration available for sub-3 W embedded communications processors with Layerscape architecture and with a comprehensive enablement model focused on ease of programmability.
