Core™-4xxx Processor
Overview
The PC4-PRESTO is a rich featured high
performance 4HP/3U CompactPCI
®
PlusIO CPU
board, equipped with a 4
th
Generation Intel
®
Core™ mobile processor (Haswell dual- or quad-
core). The PC4-PRESTO front panel is provided
with two Gigabit Ethernet jacks, two USB 3.0
receptacles, and two Mini DisplayPort
connectors, compliant with the DisplayPort 1.2
standard for Multi-Stream-Transport (MST).
Local expansion mezzanine boards (side cards)
are available for additional front panel and/or
rear I/O, resulting in an 8HP front panel width
assembly unit.
The PC4-PRESTO is equipped with up to 16GB
RAM with ECC support. 8GB memory-down are
provided for rugged applications, and another
8GB are available via the DDR3 ECC SO-DIMM
socket. Low profile SSD mezzanine modules are
available as on-board mass storage solution,
maintaining the 4HP front panel width. The
PC4-PRESTO backplane connectors comply with
the PICMG
®
CompactPCI
®
PlusIO system slot
specification, via J2 suitable for a rear I/O
module or hybrid CompactPCI
®
Serial system.
The PC4-PRESTO is backwards compatible to
classic CompactPCI
®
systems.
CompactPCI
®
PlusIO (PICMG 2.30) is a new
standard for rear I/O across J2, specified by the
PICMG
®
. High speed signal lines (PCI Express
®
,
SATA, Gigabit Ethernet and USB) are passed
from the PC4-PRESTO through the special UHM
connector to the backplane, for usage either on
a PlusIO rear I/O transition module, or
CompactPCI
®
Serial card slots.
CompactPCI
®
Serial (PICMG CPCIS.0) defines a
completely new card slot, based on PCI
Express
®
, SATA, Gigabit Ethernet and USB serial
data lines. On a hybrid backplane, both card
styles can reside, CompactPCI
®
and
CompactPCI
®
Serial, with the PC4-PRESTO in the
middle as system slot controller for both
backplane segments.
The PC4-PRESTO is equipped with a set of local
expansion interface connectors, which can be
optionally used to attach a mezzanine side
board. A variety of expansion cards is available,
e.g. providing legacy I/O and additional PCI
Express
®
based I/O controllers such as SATA,
USB 3.0 and Gigabit Ethernet, or a third video
output. Most mezzanine side cards can
accommodate in addition a 2.5-inch drive.
Typically, the PC4-PRESTO and the related side
card would come as a readily assembled 8HP
unit. As an alternate, low profile Flash based
mezzanine storage modules are available that
fit on the PC4-PRESTO while maintaining the
4HP profile. The C48-M2 module e.g. is
equipped with two fast M.2 SATA Solid State
Drives (SSD), which is suitable for installation of
any popular operating system.
