Introduction
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.
