QorIQLS1ProcessorFamily
QorIQ LS1020A and LS1022A
Communications Processors
Dual-core solutions for power-sensitive networking
and industrial applications
Overview
TheQorIQLS1020AandLS1022Aprocessorsarecost-effective,power-efficientandhighly
integratedsystem-on-chipdesignsthatextendthereachofthevalue-performanceproductline
forenterpriseandconsumernetworkingapplications.IncorporatingdualARM®Cortex®-A7cores
withECCprotectionrunningupto1.0GHz,theQorIQLS1020AandLS1022Aprocessorsare
engineeredtodeliveroutstandingefficiency,deliveringover5,000CoreMarks®ofperformance,
aswellasvirtualizationsupport,advancedsecurityfeaturesandthebroadestarrayofhigh-speed
interconnectsandserialconnectivityoptionseverofferedinasub-3Wprocessor.
Core Complex
TheQorIQLS1020AandLS1022AprocessorsbothintegratedualARMCortex-A7coresrunning
upto1.0GHz(600MHzontheLS1022A)withECC-protectedL1andL2caches.Thedual
coreseachfeature32KBofL1instructionanddatacacheandshareupto512KBofcoherent
L2cache,aswellassingle-biterrordetectandcorrectionforbothL1andL2caches.BothARM
Cortex-A7coresintheLS1020AandLS1022AprocessorsfeaturetheNEONSimDmoduleand
dual-precisionfloating-pointunit(FPU).TheDDRmemorycontrollersupports8-,16-or32-bittype
3Landfourmemorydevicesatupto1,600MHz(LS1022AlimitedtoDDR3Latupto1,033MHz).
