From Parallel to Serial
COM Express™ modules are highly integrated off-the-shelf building blocks based
on a PCI Express® bus architecture that plug into custom made, application-speci c
carrier boards. COM Express™ modules measure just 95 mm x 125 mm and include
most generic functions such as video, audio, Ethernet, storage interfaces, and
USB ports that are needed for most applications. A custom designed carrier board
complements the COM Express™ core module with additional functionality required
for a speci c application.
COM Express™ is a result of the convergence of the latest technology standards
based on serial differential signalling such as PCI Express® USB 2.0, Serial ATA, LVDS,
and Serial DVO implemented on an extremely compact Computer-on-Module. Moving
from parallel busses such as PCI™ and IDE to serial busses such as PCI Express® is
achange the scale of which has not been seen since PCI™ replaced ISA.
