LOTR (Lord Of The RISCs)

  • Type: ANR PRC, Oct 2023 – Sept 2027
  • Partners: TARAN, PACAP, CEA-List
  • Objective: Lord Of The RISCs (LOTR) is a novel flow for designing highly customized RISC-V processor microarchitectures for embedded and IoT platforms. The LOTR flow operates on a description of the processor Instruction Set Architecture (ISA). It can automatically infer synthesizable Register Transfer Level (RTL) descriptions of a large number of microarchitecture variants with different performance/cost trade-offs. In addition, the flow integrates two domain-specific toolboxes dedicated to the support of timing predictability (for safety-critical systems) and security (through hardware protection mechanisms).

RADYAL (Resource-Aware DYnamically Adaptable machine Learning)

  • Type: ANR PRC, Oct 2023 – Apr 2027
  • Partners: LIRIS / INSA Lyon, Inria (TARAN, Ctrl-A), GIPSA-lab / UGA
  • Objective: Nowadays, for many applications, the performance requirements of a DNN model deployed on a given hardware platform are not static but evolving dynamically as its operating conditions and environment change. RADYAL studies original interdisciplinary approaches that allow DNN models to be dynamically configurable at run-time on a given reconfigurable hardware accelerator architecture, depending on the external environment, following an approach based on feedback loops and control theory.

Re-Trusting (REliable hardware for TRUSTworthy artificial INtelliGence)

  • Type: ANR PRCE, Jan. 2022 – Sep. 2025.
  • Partners: INL, LIP6, TARAN, THALES.
  • Objective: The RE-TRUSTING project develops fault models and performs failure analysis of HW-AIs to study their vulnerability with the goal of “explaining” HW-AI. Explaining HW-AI means ensuring that the hardware is error-free and that the AI hardware does not compromise the AI prediction accuracy and does not bias AI decision-making. In this regard, the project aims at providing confidence and trust in decision-making based on AI by explaining the hardware wherein AI algorithms are being executed.

  • Type: ANR young researcher, Feb. 2022 – Dec. 2025.
  • Partners: TARAN (PI:A. Kritikakou).
  • Objective: FASY will answering the two-fold challenge of time-predictable and reliable multicore systems through functional and timing analysis of applications behaviour, fault-aware WCET estimation and design of cores with time-predictable execution, under faults.

LeanAI (Dynamic Precision Training on the Edge)

  • Type: Labex CominLabs, Oct. 2021 – Sep. 2024.
  • Partners: TARAN, LS2N/OGRE, INRIA-LIP/DANTE.
  • Objective: LeanAI will attack the problem of training deep neural networks on edge devices at the arithmetic and algorithmic levels and explore the design of new mixed numerical precision hardware architectures that are at the same time more energy-efficient and offer increased performance in a resource-restricted environment. The expected outcome of the project includes new mixed-precision algorithms for neural network training, together with open-source tools for hardware and software training acceleration at the arithmetic level on edge devices.

Sniffer (Non-intrusive monitoring of mains operated equipment)

  • Type: Feb. 2020 – Dec. 2022.
  • Partners: TARAN, DGA/MI.
  • Objective: Based on the SmartSense platform and on high-frequency traces of the power consumption of individ- ual electrical appliances and building-level power monitoring, the aim of Sniffer is the detection and surveillance of equipment connected to the mains supply.

  • Type: ANR young researcher, Feb. 2019 – Jan. 2022.
  • Partners: TARAN (PI: C. Killian).
  • Objective: Study the process compatibility of ONoC, WiNoC and Electrical NoC, to define a topology of an architecture hybridizing these three technologies, and to demonstrate that this architecture is more efficient with respect to traffic characteristics between cores and quality of service targeted.
