LS1024ASN7JLA
微处理器 - MPU 2 cores @ 900MHz PCIe DDR3 VoIP
Overview
The QorIQ® LS102MA and LS1024A multicore communications processors delivers scalability, superior packet handling capabilities, vastly increased VPN and SSL throughput and industry leading quality of service hardware features. For broadband home routers, VoIP gateways, IoT Internet of Things gateways, and low-end network attached storage.
Based on single- or dual-core Arm® Cortex®-A9 CPU cores, the QorIQ LS1024A of system-on-chip SoC processor achieves the lowest power consumption in its class <3 W typical at 900 MHz to provide performance scalability and maximum flexibility. In addition to high throughput IPSec and SSL CPU offload with an onboard security engine that includes a powerful deep packet inspection engine with GZIP decompression capability. The LS1024A processor includes SATA-2 interfaces, along with a powerful processing engine and integrated RAID controller to provide an ideal solution for network attached storage applications.
The QorIQ LS1024A OpenWRT Linux-based SDK is optimized for both single- and dual-core operation. The software deliverables for the LS1024A dual-core devices are backward compatible with the LS102MA devices.
