  • Efficient reconfigurable entropy coder for embedded multi-standards video adaptation
    CVPR 2011 WORKSHOPS, 2011
    Co-Authors: N. Marques, Hassan Rabah, Eric Dabellani, S Weber
    Abstract:

    This paper presents an efficient reconfigurable entropy encoder for real time adaptation of multi-standard compressed video stream. The proposed embedded architecture is based on partial and dynamic reconfiguration. Static and dynamic wrappers are defined to encapsulate different types of entropy coders with efficient swapping capabilities for Context Saving and restoring. The wrappers are designed to reduce the area overhead. A partitioning of reconfigurable area is also presented aiming at the optimization of reconfiguration overhead. The obtained results show a significant gain up to 40% in silicon area compared to a solution without reconfiguration and a significant gain of 23% in reconfiguration time. Thanks to reconfigurable entropy coder, it is possible to treat MPEG-2 and H.264 video streams meeting its real time constraints using dynamic reconfiguration.

  • SECCS: SECure Context Saving for IoT Devices
    arXiv: Cryptography and Security, 2019
    Co-Authors: Emanuele Valea, Mathieu Da Silva, Giorgio Di Natale, Marie-lise Flottes, Sophie Dupuis, Bruno Rouzeyre
    Abstract:

    Energy consumption of IoT devices is a very important issue. For this reason, many techniques have been developed to allow IoT nodes to be aware of the amount of available energy. When energy is missing, the device halts and saves its state. One of those techniques is Context Saving, relying on the use of Non-Volatile Memories (NVM) to store and restore the state of the device. However, this information, as far as IoT devices deal with security, might be the target of attacks, including tampering and theft of confidential data. In this paper, we propose a SECure Context Saving (SECCS) approach that provides a Context Saving procedure and a hardware module easy to implement inside a System on Chip (SoC). This approach provides both confidentiality and integrity to all the CPU content saved into the target NVM.
