COM Express Type 1 carrier board expansion
in the COM Express carrier board implementation the external IO from the module is
provided via the COM Express board-to-board connector. The carrier board can be
implemented using a method that best suits your needs.
Processor and chipset
Intel ATOM processor
The Intel ATOM Z5xx series processor is a high-performance, ultra low power processor
with several microarchitectural enhancements over existing Intel mobile processors. The
ATOM Z5xx series offers the benefits of the following Intel architecture for small form
factor, thermally constrained and fanless embedded systems:
•
Intel's 45nm technology, based on a Hafnium, high-K metal gate formula, reduces
power consumption, increases switching speed, and significantly increases transistor
density over the previous 65nm technology.
•
Multiple micro-ops per instruction are combined into a single micro-op and executed
in a single cycle, resulting in improved performance and power savings.
•
in-order execution core consumes less power than out-of-order execution.
•
Hyper-Threading Technology (HT Technology; 1.6 GHz SKU only) provides high
performance-per-watt efficiency in an in-order pipeline. HT Technology provides
increased system responsiveness in multi-tasking environments. One execution core
is seen as two logical processors, and parallel threads are executed on a single core
with shared resources.
US15W System Controller Hub
The US15W is a single-chip System Controller Hub (SCH) that consists of an integrated
graphics controller, a memory controller, and I/O controller. The SCH combines the
functionality normally found in separate GMCH (front side bus interface, integrated
graphics and memory controller) and ICH (platform I/O expansion) components, in a
single device providing the functionality necessary to support fully featured operating
systems.
The Intel
®
System Controller Hub US15W combines the Intel
®
Graphics Media
Accelerator 500 (Intel
®
GMA 500), memory controller, and I/O controller in a single-chip
solution. It also features advanced 3D graphics and extensive I/O capabilities such as
USB 2.0, SDIO and PCI Express. Additionally, it supports Intel
®
High Definition Audio,
hardware video decode acceleration, a 400/533 MHz CMOS front-side bus (FSB), dual
independent display and 1 GB memory.
