Configuration server for self-adaptive architectures

This paper presents a network-based solution to efficiently manage configurations of reconfigurable Multiprocessor system on chip. We first define our R-MPSoC architecture and the concept of on-the-fly reconfiguration management. Then two issues are discussed and some solutions are presented: (1) formalization of configuration protocol and (2) synchronization of configuration. The second point mainly addresses the issue of on-the-fly reconfiguration flow and the way a process accepts a new configuration. Finally, we present the global method and give several implementation results from a MP3 player case study.
