Dear Readers,
                                     Once again this issue of ECE mag-
                                     azine highlights some of the major
                                     trends in the embedded market-
                                     place. The first one - becoming a
                                     solution provider - isn’t really new,
                                     but reached new levels. Two years
                                     ago EBV created the so called
                                     EBVchips program in which the
                                     distributor started to develop spe-
                                     cialised semiconductor products
                                     for customers. These new products
                                     are closing the gap between appli-
                                     cation specific standard products
                                     (ASSPs) and application specific
                                     integrated circuits (ASICs). ASICs
                                     are or would be often the optimal
                                     solution for certain applications
of one user but are not economical due to the inherent high develop-
ment and NRE cost. It needs extremely high volume to justify their
use. In addition – once developed – they are not flexible enough, to be
adapted to new requirements. ASSPs are very similar o ASICs but not
limited to one user they serve a certain application for multiple users.

According to Wikipedia is an ASSP an integrated circuit that implements
a specific function that appeals to a wide market. As opposed to ASICs
that combine a collection of functions and designed by or for one cus-
tomer, ASSPs are available as off-the-shelf components and are used
in all industries, from automotive to communications. Examples of
ASSPs are integrated circuits that perform video and/or audio encoding
and/or decoding. EBVchip products are comparable to ASSPs but are
virtually free of development and NRE cost for the user – this is taken
over by the distributor. Therefore he has to decide whether the
product to develop has a suitable market potential to create additional
revenue for both the manufacturer und the distributor. If this is the
case a triple win situation is created: more revenue for the manufacturer
and distributor and a optimized device for the user. In the meantime
this advantage is well accepted in the embedded market place – there
are over 20 projects in the pipeline and the results of some of them
will be presented at electronica 2012 in Munich. In our cover story the
first two products in the EBVchip program are described and I m
curious about what we will see at electronica.

Further major trends are energy saving, interconnection via the
internet, and even energy harvesting. It is becoming increasingly
clear that energy saving is a holistic occupation – it cannot be done in
isolation. However, implementing such a holistic approach requires
that product designers, architects and IT professionals have at their
disposal a technique for interconnecting e.g. all types of things within
buildings – and beyond to the wider internet. This not only allows re-
mote devices and central computers to control the operation of indi-
vidual elements, it also permits feedback and monitoring that enables
more sophisticated control strategies. Smart energy technology already
exists to cost-effectively embed great intelligence in individual products
and appliances. You ll find examples for these trends in his issue, too.

Enjoy!

Yours sincerely

EBVchips gains momentum
in the embedded marketplace
By Wolfgang Patelay


          The idea behind EBVchips as
           a distributor not only selling
suppliers’ products but also designing
      specific semiconductor products
     based on the requirements of its
  customers was born in 2010, and is
 now well accepted in the embedded
         industry. Antonio Fernandez,
   Director Technical Marketing, EBV,
           explains the reasons for this
   new service and gives an overview
           of the current situation and

Wireless-enabled MCUs – joining the
dots to reveal the energy-saving future
By Colin Faulkner, NXP Semiconductors


             With energy prices soaring
              and a new climate change
                protocol on the horizon,
                 albeit belatedly, there is
               a continuing drive to save
            energy in our everyday lives.

Avoid enemies and make friends
with embedded open source software
By Mahshad Koohgoli, Protecode


                       Open source software
                       invariably comes with
                associated license and other
                    obligations that must be
                       respected. This article
                describes a structured open
                   source software adoption
                process (OSSAP) that allows
                        organizations to take
                  advantage of open source

Verification of FPGA software:
a simulating issue
