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