Digital Embedded Systems and IoT

This research line is focused on the design of digital embedded systems implemented on programmable devices (FPGAs), using intellectual property (IP) modules. The aim is to solve problems related to size constraints, power consumption and computation that characterize such systems, as well as to provide the tools and design methodologies that facilitate and accelerate its development. The highlights of the developed solutions are the design of specific processing architectures, hardware/software codesign techniques, the use of reconfigurable devices, and the employment of Intellectual Property (IP) modules for reusability. The transversal nature of this research line allows that its results can be used in different application domains related to other research activities of the group.

The topics of interest that are covered by this research line are:

  • Development of design methodologies for embedded digital systems.
    - Specification languages.
    - Hardware & software codesign.
    - CAD tools development.
  • Architectures for specific application systems.
    - Architectures and design of data/signal processing modules
    - Development of IP modules.
    - Reconfigurable systems
  • Applications of embedded digital systems.
    - Biometric systems based on fingerprint, face and voice.
    - Cryptographic systems
    - Image processing and artificial vision
    - Emerging applications of wearables, smart cards, communications networks, industrial control systems, wireless sensor networks and Internet of Things.
