1-2 Processor Overview
The A1SAi/A1SRi Series motherboard supports a 2nd-generation 64-bit, Intel®
Atom™ C2000 Tri-Gate SoC (System-on-a-Chip) processor based on low-power
Silvermont microarchitecture in an FCBGA 1283 package. Built upon the func-
tionality and capability of the C2000 Series processor in the low-power 22nm
microarchitecture, the A1SAi/A1SRi Series motherboard provides unprecedented
enhancements to network routing, internet security, system performance, and power
efciency.
The C2000 SoC Series processor features an Out-of-Order Execution Engine and
offers new multi-core and system fabric architecture capable of utilizing eight CPU
cores to achieve improved single-thread performance. This new SoC processor also
provides an operating range with wider dynamic power and enhanced power man-
agement. In addition, the A1SRi Series motherboard supports the Intel® Quickassist
Technology, which provides hardware acceleration to help enhance cryptographic
performance, secure internet trafc, and boost network routing, freeing up processor
resources for application processing, while the A1SAi Series motherboard supports
the Intel® Turbo Boost Technology, which offers turbo-boost capabilities to maximize
system performance.
