QorIQ is a brand of ARM-based and Power ISA-based communications microprocessors from NXP Semiconductors (formerly Freescale). It is the evolutionary step from the PowerQUICC platform, and initial products were built around one or more e500mc cores and came in five different product platforms, P1, P2, P3, P4, and P5, segmented by performance and functionality. The platform keeps software compatibility with older PowerPC products such as the PowerQUICC platform. In 2012 Freescale announced ARM-based QorIQ offerings beginning in 2013. The QorIQ brand and the P1, P2 and P4 product families were announced in June 2008. Details of P3 and P5 products were announced in 2010. QorIQ P Series processors were manufactured on a 45 nm fabrication process and was available in the end of 2008 (P1 and P2), mid-2009 (P4) and 2010 (P5). QorIQ T Series is based on a 28 nm process and is pushing a very aggressive power envelope target, capping at 30 W. These are using the e6500 core with AltiVec and are expected to be shipping in 2013. QorIQ LS-1 and LS-2 families are ARM based processors using the Cortex A7, Cortex A9, A15, A53 and A72 cores upon the ISA agnostic Layerscape architecture. They are available since 2013 and target low and mid range networking and wireless infrastructure applications. 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
