AMD EMBEDDED SOLUTIONS GUIDE

JULY 2013

here was a time not so long

ago when the term “embedded

system” meant some micro-

processor or microcontroller-

based device buried in equip-

ment like a factory machine, a gas pump

or a vehicle. It was usually dedicated to a

single function and if it had a user inter-

face at all, it would be limited to a couple

of lights or buttons and perhaps a small

LCD display. But then we started con-

necting them and the world hasn’t been

the same since.

Today we stand on the threshold of a

new era of almost universally connected

intelligence from small, distributed de-

vices to ﬂeets of vehicles and aircraft,

with lines running from manufacturing

facilities all the way to retail outlets and

the consumers themselves. e list goes

on. Behind it lie several basic phenom-

ena—the incredible scales of integration

in silicon and the worldwide explosion

of connectivity—increasingly wireless—

and mostly united by the Internet Pro-

tocol. Scales of silicon integration have

been accompanied by major reductions

in the power consumption of such de-

vices, which has enabled the integration

of machine intelligence into very small,

mobile and distributed devices many of

which can be left unattended for long pe-

riods of time.

e available compute power and

connectivity are taking us to a time when

the smallest devices can communicate

with networked levels above them and

Things

the Cloud. Also part of the cloud will

be corporate IT systems and proprietary

applications and databases residing on

leased Cloud space. So there will be

clouds within the Cloud but these will

all potentially be able to share data as al-

liances, agreements and business inter-

ests determine. There will also be a large

amount of Cloud-based data and options

that are publically available.

While the upper level of the Cloud is

essential, the foundation of this growing

new realm is the Internet of ings, the

devices that interact with the real world

and with real users. And the foundation of

the Internet of ings is the vast number

of powerful, mobile and connected de-

vices that has grown out of the advances

in silicon and their connectivity because

intelligence plus connectivity results in

greater intelligence.

ultimately over the Internet to what we

now call the Cloud, the realm of the In-

ternet where vast amounts of data and

applications that can analyzed and use

that data reside. While the traditional

Internet is still very alive and well, it has

been joined by an even larger “Internet

of ings.”

e Internet of ings grew out of

what we used to call machine to machine

systems. ese were intelligent nodes that

communicated with each other autono-

mously or semi-autonomously and were

dedicated to a particular application such

as a ﬂeet management system. Now such

systems share data and communicate with

all manner of diﬀerent devices as well as

on up to the IT world. us what has

come to be called “Big Data” is mostly

generated by billions of embedded con-

nected devices.

Not only are these devices con-

nected to each other and the Internet,

they are increasingly available to mil-

lions of users through smartphones and

tablets and this is, again, made possible

by the availability of powerful, low-

power processors with rich graphics ca-

pabilities. Thus we have witnessed the

blurring of the former distinctions be-

tween the world of IT, embedded sys-

tems and those between industrial and

consumer devices.

The Big Data generated by huge

numbers of small devices will be ab-

sorbed by larger systems—server farms

scattered around the world making up
