User Guide • SC2-PRESTO • CompactPCI®Serial CPU Board • Intel® CoreTM 4xxx Processor
Overview
The SC2-PRESTO is a rich featured high
performance 4HP/3U CompactPCI®Serial CPU
board, equipped with a 4th generation Intel®
Core™ mobile processor (Haswell dual- or quad-
core). The SC2-PRESTO front panel is provided
with two Gigabit Ethernet jacks, two USB 3.0
receptacles, and two mDP connectors,
compliant with the DisplayPort 1.2 standard for
Multi-Stream-Transport (MST). Local expansion
mezzanine cards are available for additional I/O.
The SC2-PRESTO is equipped with up to 16GB
Low Power RAM with ECC support. 8GB
memory-down are provided for rugged
applications, and another 8GB are available via
the DDR3L ECC SO-DIMM socket. The on-board
SATA 6G RAID controller allows for powerful
mass storage solutions via the CompactPCI®
Serial backplane. Low profile SSD mezzanine
modules are available as on-board storage
solution, in addition.
While mechanically compliant to CompactPCI®
Classic, CompactPCI®Serial (PICMG® CPCIS.0)
defines a completely new card slot, based on
PCI Express®, SATA, Gigabit Ethernet and USB
serial data lines. Up to 6 high-speed backplane
connectors P1 - P6 are provided on a system
slot controller such as the SC2-PRESTO, which
can be considered as a root hub with respect to
most signal lines. A passive backplane is used
for distribution of a defined subset of I/O
channels from the system slot to each of up to
eight peripheral slots in a CompactPCI®Serial
system.
Most CompactPCI®Serial peripheral slot cards
require only the backplane connector P1, which
comprises PCIe, SATA and USB signals, resulting
in a concise and inexpensive peripheral board
design. More powerful peripheral cards profit
from so called Fat Pipe slots (PCIe x 8).
The SC2-PRESTO is a native CompactPCI®Serial
CPU card, suitable for usage in a pure CPCI
Serial environment. Due to its generous
backplane capabilities (22 x PCI Express® lanes,
6 x USB2, 2 x USB3, 7 x SATA/RAID, 2 x GbE),
very powerful industrial systems can be built.
The SC2-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 SC2-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 SC2-PRESTO while maintaining the
4HP profile. The C47-MSATA module e.g. is
equipped with two very fast MSATA Solid State
Drives (SSD), which is suitable for installation of
any popular operating system.

Microprocessor
The SC2-PRESTO is equipped with an Intel® CoreTM i7, i5 or i3 4th generation mobile ECC processor
(code name “Haswell”). These low power processors provide integrated graphics, memory controller
and voltage regulators, which results in a very efficient platform design.
The CoreTM i7/i5/i3 processor family includes units with several thermal design power (TDP) classes to
fit the customers requirements: 47W, 37W and 25W. The processors are housed in a Micro FC-BGA
package for direct soldering to the PCB, i.e. the chip cannot be removed or changed by the user.
The processors supported by the SC2-PRESTO are running at core clock speeds up to 2.4GHz for quad
core and up to 2.7GHz on dual core devices. Due to Enhanced Intel® SpeedStep® and Intel® Turbo
Boost Technology each core can decrease or increase its nominal operating frequency. The clock speed
is chosen depending on the power states of the processor cores/graphics engine, the currently
required performance, and the actual core temperature.
Power is applied across the CompactPCI®connector P1 (12V). The processors core voltage are
generated by a switched voltage regulator according to Intels VR12.5 voltage regulator specification.

Thermal Considerations
In order to avoid malfunctioning of the SC2-PRESTO, take care of appropriate cooling of the processor
and system, e.g. by a cooling fan suitable to the maximum power consumption of the CPU chip
actually in use. The processor contains digital thermal sensors (DTS) that are readable via special CPU
registers. DTS allows to get the temperatures of each CPU core separately.
Two further temperature sensors, located in the system hardware monitor LM87, allows for
acquisition of the boards surface temperature and the thermal state of the onboard system memory
channel. Beside this the LM87 also monitors most of the supply voltages. A suitable software on
Microsoft Windows® systems to display both, the temperatures as well as the supply voltages, is
Speedfan, which can be downloaded from the web. After installation, both temperatures and
voltages can be observed permanently from the Windows® taskbar.
The SC2-PRESTO is equipped with a passive heatsink. Its height takes into account the 4HP limitation
in mounting space of a CompactPCI®board. In addition, a forced vertical airflow through the system
enclosure (e.g. bottom mount fan unit) is strongly recommended (>20m3/h or 2m/s (400LFM) around
the CPU slot). Be sure to thoroughly discuss your actual cooling needs with EKF. Generally, the faster
the CPU speed the higher its power consumption. For higher ambient temperatures, consider
increasing the forced airflow to 3m/s (600LFM) or more.
The table showing the supported processors above give also the maximum power consumption (TDP)
of a particular processor. Fortunately, the power consumption is by far lower when executing typical
Windows® or Linux tasks. The heat dissipation increases when e.g. rendering software like the
Acrobat Distiller is executed.
The CoreTM processors support Intel's Enhanced SpeedStep® technology. This enables dynamic
switching between multiple core voltages and frequencies depending on core temperature and
currently required performance. The processors are able to reduce their core speed and core voltage
in multiple steps down to 800MHz. Additional a reduction of the graphics core clock (down to
200MHz) and voltage is possible. This leads to an obvious reduction of power consumption resulting
in less heating.
A further way to reduce power consumption is achieved by integrating the voltage regulators on the
die of the 4th generation CoreTM processors. This embedding allows the processor to regulate the
voltages to each core, graphics, cache and other units separately depending on their performance
needs. Parts that are currently idle may switched off to save power.
