QorIQ LS1046A FEATURES

Features

Benefits

2 MB L2 cache

• Total power under 10 W at 1.2 GHz for convection cooled designs

Packet processing acceleration

• Efficient packet classification and distribution; hardware work

scheduling, shaping, and buffer management, offloading the general

purpose processors to concentrate their processing cycles on value

added operations.

Integrated security engine

• High-speed security protocol processing, including IPsec, SSL,

DTLS, and IKE

• SEC also supports high speed XORing for RAID 5 acceleration

trust architecture

• Secure boot, secure debug, tamper detection, secure key storage

Rich connectivity

• Two 10 Gigabit Ethernet controllers

• One 2.5 Gigabit Ethernet controller

• Four 1 Gigabit Ethernet controllers

x 2, x 1

• Three USB 3.0 with integrated PHY

• SATA 3.0 controller

• Quad SPI

• High versatility that enables support for 802.11ac modules and

high bandwidth connectivity for ASICs, 4G/LTE, SATA and low-cost

NAND/NOR Flash

• Multiple USB 3.0 for redundant WAN fail over, storage and

configuration

• Advanced XFI, Quad SGMII for maximum Ethernet flexibility

Support for hardware-based

virtualization

• Enables partitioning of physical and virtual resources on LS1046A

multicore devices for increased system flexibility
