The LS1043A processor was NXP's first quad-core, 64-bit Arm-based processor for embedded networking. LS1023A (two-core version) and LS1043A (four-core version) deliver greater than 10 Gbps of performance in a flexible I/O package supporting fanless designs. This SoC is a purpose-built solution for small-form-factor networking, industrial and automotive applications with BOM optimizations for economical low layer PCB, lower-cost power supply and single clock design.

The new 0.9V versions of the LS1043A and LS1023A deliver additional power savings for applications such as Wireless LAN and to Power over Ethernet systems. The 23x23 package options allow for pin-compatible design, enabling scaling to the LS1046A (quad A72 processor) or LS1088A (octal A53 core processor).
The first flash-based SSDs leveraged legacy SATA/SAS physical interfaces, protocols, and form factors to minimize changes in the existing hard drive (HDD)-based enterprise server/ storage systems. However, none of these interfaces and protocols were designed for high-speed storage media (i.e. NAND and/ or persistent memory). Because of the interface speed, performance of the new storage media, and proximity to the CPU, PCI Express (PCIe) was the next logical storage interface.
NVMe is a high-performance, NUMA (Non Uniform Memory Access) optimized, and highly scalable storage protocol, that connects the host to the memory subsystem. The protocol is relatively new, feature-rich, and designed from the ground up for non-volatile memory media (NAND and Persistent Memory) directly connected to CPU via PCIe interface (See diagram #1). The protocol is built on high speed PCIe lanes. PCIe Gen 3.0 link can offer transfer speed more than 2x than that of SATA interface.
