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