What is an embedded system?


We live surrounded by embedded systems

Typical characteristics of an embedded system

Embedded systems often have one
or more of the following features:

  1. Reduced power consumption
  2. Reduced size
  3. Low cost per unit
  4. High Reliability
  5. Reduced (zero) need of maintenance

Example: In-Vehicle Infotainment

Hardware commoditization

  • Thanks to Moore's law, embedded systems have now enough computing power to allow adaptation and reuse of complex software originally developed for servers and desktops
      • Networking stacks and protocols
      • User Interface frameworks
      • Open Source software
  • With the economy of scale achieved by smartphones and other consumer devices, complex computer architectures have become affordable also for embedded systems
  • On the other hand, developing dedicated, custom hardware and porting standard platform software requires a huge investment and becomes justified only for high volume productions

Example: GENIVI Demo Platform

$ sloccount gdp_ivi9_beta/workspace

Totals grouped by language (dominant language first):

ansic:     46260693 (69.83%)
cpp:        9910207 (14.96%)
asm:        2006557 (3.03%)
sh:         1575972 (2.38%)
perl:       1276566 (1.93%)
python:     1163866 (1.76%)
xml:        1054193 (1.59%)


Total Physical Source Lines of Code (SLOC) = 66,247,653

Example: Android 5.1.1

$ sloccount build_android_udooneo/workspace

Totals grouped by language (dominant language first):
ansic:     28909496 (48.66%)
cpp:       14820059 (24.95%)
xml:        6894345 (11.61%)
java:       5651249 (9.51%)

sh:          434135 (0.73%)
perl:        197439 (0.33%)


Total Physical Source Lines of Code (SLOC) = 59,405,160

Standard HW/SW Platforms are
becoming mainstream

  • Low-cost building blocks to prototype embedded systems
  • Complete with a ready-to-go Open Source software stack
  • Widely used hardware interfaces
  • Available for PoC and low-volume production
  • Can speed up and reduce risk in embedded system design

UDOO X86: The definition
of "embedded system" is broadening...


  • Embedded Systems: more features, more capabilities
      • HW is becoming a commodity unless for huge volumes
      • SW development and system validation becomes the issue

  • Low-cost, standard HW platforms are now available - complete with a broad choice of Open Source software
      • Standard Web Frameworks and Tools are now affordable also on many types of embedded systems

  • Relying on proven and validated HW/SW platforms
    allows embedded system developers to focus on application level and maximize the value to the end user
