GENERAL PURPOSE PROCESSORS
The QorIQ LS1043A processor leverages the 64-bit ARM
Cortex-A53 core to deliver leading edge performance with
high energy efficiency. This new quad- or dual-core complex
provides a generous 1MB L2-cache and a highly efficient
eight-stage pipeline for maximum performance per watt.
The QorIQ LS1043A processor uses the high performance
CoreLink CCI 400™ coherent interconnect with the SMMU
(ARM’s I/O MMU) to provide hardware enforced memory
access controls for accelerators and peripherals operating
on behalf of virtual machines running on the general
purpose processors.
The LS1023A (two core version) and the LS1043A (four core
version) deliver greater than 10 Gb/s of performance in a
flexible I/O package supporting fanless designs. This SoC is
a purpose-built solution for small-form-factor networking and
industrial applications with BOM optimizations for economic low
layer PCB, lower cost power supply and single clock design.
The QorIQ LS1043A delivers a next-generation performance
boost over dual-core ARM 32-bit products such as the QorIQ
LS1020A and the LS1024A processors. The LS1043A takes
ARM processing performance to the next level with up to 4x
1.6 GHz 64-bit processors and a large 1 MB L2-cache for the
best CPU performance per watt in the value-tier line of QorIQ
communications processors. This powerful CPU complex is
coupled with the proven offload engines of the QorIQ Data
Path Acceleration Architecture (DPAA) to deliver up to 10
Gb/s performance with minimal CPU overhead.
