Layerscape
The Layerscape (LS) architecture is the latest evolution of the QorIQ family, in that features previously provided by DPAA (like compression) may be implemented in software or hardware, depending on the specific chip, but transparent to application programmers. LS-1 and LS-2 are announced to use Cortex A7, A9, A15, A53 and A72 cores. The initial LS-1 series does not include any accelerated packet processing layer, focusing typical power consumption of less than 3W using two Cortex A7 with providing ECC for caches and DDR3/4 at 1000 to 1600 MT/s, dual PCI Express Controllers in x1/x2/x4 operation, SD/MMC, SATA 1/2/3, USB 2/3 with integrated PHY, and virtualized dTSEC Gigabit Ethernet Controllers. LS1 means LS1XXX series (e.g., LS1021A, etc.); LS2 means LS2XXX series. LS2 means a higher performance level than LS1, and it does not indicate a second generation. The middle two digits of the product name are core count; the last digit distinguishes models, with, in most but not all cases, a higher digit meaning greater performance. “A” at the end indicates the Arm processor. LX designates the 16 nm FinFET generation. The LS1 family is built on the Layerscape architecture is a programmable data-plane engine networking architecture. Both LS1 and LS2 families of processors offer the advanced, high-performance datapath and network peripheral interfaces. These features are frequently required for networking, telecom/datacom, wireless infrastructure, military and aerospace applications.Initial announcement

Networking, IT and telecommunication systems
The QorIQ products bring some new challenges in order to design some control planes of telecommunication systems and their data plane. For instance, when 4 or 8 cores are used, such as the P4080, in order to achieve millions of Packet Processing per seconds, the system does not scale with ''regular software stack'' because so many cores require a different system design. In order to restore simplicity and still get the highest level of performance, the telecommunication systems are based on a segregation of the cores. Some cores are used for the control plane while some others are used for a re-designed data plane based on a Fast Path. Freescale has partnered with networking company 6WIND to provide software developers with a high-performance commercial packet processing solution for the QorIQ platform.See also
