Welcome to the ADAM project home page
What is ADAM ?
ADAM stands for "Adaptive Dynamic Architecture for MP2SoCs". It is a prospective research project that directly addresses the hot topic of MPSoC self-adaptability to altered operating conditions, like loss of performance, appearance of faulty hardware resources, and temperature overhead. The architectures targeted by ADAM are MP2SoC, Massively Parallel Multi-Processor systems on chip (more than one hundred of processing elements) containing homogeneous functional blocks (all blocks can perform the work requested by the application), but structurally heterogeneous (with different and process dependant performances, electrical and timing characteristics and reliability). Taking simultaneously these problems into account is mandatory to ensure the reliability and competitiveness of embedded systems to come.
Three French laboratories with international reputation have joined their effort to propose a unified approach to the self-adaptability in MP2SoC issue. Considering a standard 2D mesh hardware architecture with a Network on Chip interconnecting clusters containing processing elements and local memories, the proposal can be summarized as a three steps process : non-intrusive online monitoring, online diagnosis/test, and online remapping. The main contribution of the ADAM project is to make these three steps finely interact through the use of onchip dynamic event databases: local databases of formatted/historized events and a global database of architecture instant maps, or architecture audited views classified by event types.
- LETI (Laboratory for Electronics & Information Technology) is operated by the Technology Department of CEA (DRT "Direction de la Recherche Technologique"), the French Atomic Energy Commission. LETI is one of the largest European applied research laboratories in the field of electronics: permanent staff is approximately 1200 people. The main activities of CEA/LETI are dealing with electronics, microelectronics, microsystems and IC design.
Its corporate goal is to bring technological innovation to the European industry, and to create added value through an active Intellectual Property policy based on the management of strong patent portfolio (> 500 active patents, and more than 140 filings/year) and the licensing of its technologies. For more than ten years, LETI has been working on wireless systems for several applications fields: medical (indoor), military (outdoor), robotics, mobiles phones and communications with mobiles (cars, trains, underground, etc.). LETI is currently involved in several R&D telecom project of the 6th Framework.
The DCIS Department (DCIS: "Conception et Intégration des Systèmes") at LETI is in charge of the IC design activities, and is currently addressing the following topics:
- digital and mixed chip design for telecom, smart cards, RFID, image processing, smart devices, etc.
- architecture exploration (HW/SW partitioning, performance evaluation, etc.)
- design flow methodology (SystemC/TLM methodology, XML/Spirit, Matlab/Simulink? co simulation, etc).
An important concern at LETI is the design of mixed signal, multi-physics systems with sensors/activators (MEMS, MOEMS, etc.), RF front-end and complex SOC design and architecture.
LETI is now reference as a world wide key actor in the field of network on chip (NOC) architecture: refer to LETI papers at the ISSCC'07 conference. An innovative Software Defined Radio platform based on fully distributed communication and control system has been designed. This architecture framework is targeting complex data flow applications. The backbone of the architecture is a layered asynchronous NOC that brings scalability at architecture level and flexibility at the application level. Silicon proves these concepts, and is currently used for complex Radio Access technology experimentation.
