NXP公司的QorIQ® LS1012A是基于64位ARM® Cortex®-A53核的低功耗通信处理器,提供超过4000的CoreMark®性能,用于包处理和安全的硬件加速器,以及1W典型功耗通信处理器最好的整体性能.工作频率高达1GHz,主要用在可信赖的IoT网关,数据中心以太网驱动,建筑物和工作自动化,消毒类电子,网络存储(电池供电),智能家庭网关等.本文介绍了QorIQ LS1012A主要特性,框图和开发板QorIQ® FRDM-LS1012A主要特性,电路图,材料清单和PCB装配图.
Incorporating a 64-bit Arm® Cortex®-A53 core, the LS1012A processor delivers CoreMark® performance of over 4,000 as well as hardware acceleration for packet processing and security, and the best overall performance of any 1 W typical power communications processor.
CORE COMPLEX
The LS1012A processor integrates a single Arm Cortex-A53 core running up to 1 GHz with ECC-protected L1 and L2 caches and incorporates the same trust architecture and software compatibility of higher-tier Layerscape family devices. The LS1012A processor features 32 KB of L1 instruction and data cache and 256 KB of coherent L2 cache. In addition, the Cortex-A53 core features the NEON™ SimD module and dual-precision floating point unit (FPU). The memory controller supports 16-bit DDR3L memory devices at 1 GHz.
