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
efficiency.
The C2000 SoC Series processor features an Out-of-Order Execution Engine and
offers new multi-core and system fabric architecture capable of utilizing up to eight
CPU cores to achieve improved single-thread performance. This new SoC proces-
sor also provides an operating range with wider dynamic power and enhanced
power management. In addition, the A1SRi Series motherboard supports the Intel
QuickAssist Technology, which provides hardware acceleration to help enhance
cryptographic performance, secure internet traffic, 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.
