5LS1021A SoC Overview
6------------------
7The QorIQ LS1 family, which includes the LS1021A communications processor,
8is built on Layerscape architecture, the industry's first software-aware,
9core-agnostic networking architecture to offer unprecedented efficiency
10and scale.
11
12A member of the value-performance tier, the QorIQ LS1021A processor provides
13extensive integration and power efficiency for fanless, small form factor
14enterprise networking applications. Incorporating dual ARM Cortex-A7 cores
15running up to 1.0 GHz, the LS1021A processor delivers pre-silicon CoreMark
16performance of over 6,000, as well as virtualization support, advanced
17security features and the broadest array of high-speed interconnects and
18optimized peripheral features ever offered in a sub-3 W processor.
19
20The QorIQ LS1021A processor features an integrated LCD controller,
21CAN controller for implementing industrial protocols, DDR3L/4 running
22up to 1600 MHz, integrated security engine and QUICC Engine, and ECC
23protection on both L1 and L2 caches. The LS1021A processor is pin- and
24software-compatible with the QorIQ LS1020A and LS1022A processors.
