This Research-Team is a follow-up of R2D2 Research-Team
The scientific aim of the CAIRN team is to study reconfigurable system-on-chip, i.e. hardware systems whose configuration may change before or even during execution. To this end, CAIRN intends to approach reconfigurable architectures from three angles: the invention of new reconfigurable platforms, the development of associated transformation, compilation and synthesis tools, and the exploration of the interaction between algorithms and architectures.
Reconfigurable systems have been considered by research and industry for some years thanks to possibilities opened up initially by Field Programmable Gate Arrays (FPGA) technology and more recently by reconfigurable processors.
Recent evolutions in technology and modern hardware systems confirm that reconfigurable systems are increasingly used in recent applications or embedded into more general system-on-chip. Rapidly changing application standards in fields such as communications and information security ask for frequent modifications of the devices. Hardware reconfiguration can adapt the system to changing conditions. Moreover, this adaptation of a flexible hardware to the application software leads to significant gain in terms of performance and energy efficiency.
However, reconfigurable systems raise several challenges like the architecture structure itself, its dynamic reconfiguration capabilities or the associated compilation/synthesis methods and tools.
Design of dynamically reconfigurable or domain-specific architectures with focus on dynamic behavior, reconfiguration management and energy efficiency
Architecture description language for reconfigurable architectures
Reconfigurable system management
Reconfigurable memory structure
Flexible arithmetic operators
Multimode components
Development of associated compilation and transformation techniques
Pattern-based compilation and configuration synthesis for reconfigurable platform
Synthesis of nested loop accelerator from C specification
Floating-point to fixed-point transformations
Multi-mode IP synthesis
Resource or energy constrained optimization of signal processing algorithms
Fixed Point accuracy analytical evaluation
Precoding schemes for 4G/MIMO systems
Cooperative MIMO for sensor networks
High-rate true random number generation
Application domains are mobile communications, wireless sensor networks, network security and video processing.
