AMD EMBEDDED SOLUTIONS GUIDE

JULY 2013

Conventional, multimedia-capable

computer systems with integrated add-

on graphics cards are generally ill-suited

for in-vehicle installations, as graphics

cards are typically mounted to right-

edge connectors within the system. An

edge connector takes up more space

(card-edge boards are typically 3” to 5”

taller) and exposes it to additional shock

and vibration that can lead to system in-

tegrity issues.

The combination of a low-power

CPU and a discrete-level GPU into a

single AMD Embedded G-Series APU

eliminates the need for bulky add-on

graphics cards for video/graphic-opti-

mized in-vehicle computing systems,

enabling Sintrones to achieve an ultra-

compact form factor for its VBOX-3200

system. The AMD APU architecture

reduces the footprint of a traditional

three-chip platform to just two chips –

the APU and the companion controller

hub. This two-chip solution simplifies

design complexity through a reduction

in board layers and power needs, and

helped enable Sintrones to achieve am-

bitious form factor goals.

The VBOX-3200’s system chassis

measures a mere 250mm (W) x 150mm

(D) x 55mm (H) – enabling the unit

to be easily slipped into tight spaces

within vehicle cabins. The system

supports a wide temperature range of

-40ºC to ~70ºC for thermally-demand-

ing environments, and also meets the

MIL-STD-810F standard for shock

and vibration.

Energy Efficiency on the

Unlike most wall-plugged com-

puting systems, in-vehicle computers

can be especially sensitive to power

consumption constraints. Low power

draw is important if a computer is to be

battery. This energy efficiency require-

ment will likely become even more

pronounced as municipalities acceler-

ate their adoption of more environmen-

tally-friendly electric and hybrid-elec-

tric vehicle fleets.

The performance-per-watt gains

enabled by AMD Embedded G-Series

APUs assure greater power efficiency

and lower heat dissipation, which, in

turn, can preclude the need for fan

cooling within in-vehicle computing

systems. Supporting thermal design

power (TDP) profiles starting at 4.5W

and up to 18W – with average power

as low as 2.3W – AMD G-Series APUs

allowed Sintrones to keep board-level

total power consumption to less than

20W, enabling its designers to optimize

VBOX-3200 systems to overcome chal-

lenging power constraints.

System cooling is, of course, an-

other critical design consideration for

in-vehicle computing systems. Fan-

cooled systems are vulnerable to air-

borne particulates and debris, as well

as considerable shock and vibration

– all of which are common environ-

mental factors for vehicle-based sys-

tems. Sintrones’ designers are therefore

understandably wary of fan cooling

mechanisms due to the inherent risk

of failure. AMD Embedded G-Series

APUs’ low power profile helped ensure

that Sintrones’ VBOX-3200 systems

can be passively cooled – no fan re-

quired.

VBOX-3200 systems accommo-

date 12V and 24V inputs from vehicle

batteries, and include optional ‘smart’

battery backup for uninterrupted power

support. The systems also feature ad-

vanced power ignition capabilities that

enable adaptability to dynamic power

supply conditions.

x86 Versatility

With AMD Embedded G-Series

APUs at the heart of its VBOX-3200

systems, Sintrones is afforded process-

ing and cost efficiencies that help its

customers maximize their return on

investment. These natural efficiencies

are amplified significantly on the un-

derlying embedded x86 platform, given

the inherent PC-compatibility and rich

ecosystem of industry-standard, x86-

optimized software, applications, op-

erating systems and development envi-

ronments available to Sintrones’ design-

ers and its customers.

x86 support also ensures greater

interoperability with the enterprise IT

network, which can introduce addi-

tional benefits for in-vehicle applica-

tions such as security and surveillance

and/or centralized fleet management

applications hosted on network infra-

structure. With AMD Embedded G-

Series APUs, Sintrones’ design team

benefitted from wide ranging operat-

ing system and driver support spanning

Linux® and Windows® Embedded envi-

ronments. These interoperability fea-

tures helped Sintrones’ designers mini-

mize design complexity and speed time

to market considerably.
