Abstract : The growing number of cores in a single chip goes along with an increase in com-munications. The variety of applications running on the chip causes spatial andtemporal heterogeneity of communications. To address these issues, we presentin this thesis a dynamically reconfigurable interconnect based on Radio Frequency(RF) for intra chip communications. The use of RF allows to increase the bandwidthwhile minimizing the latency. Dynamic reconfiguration of the interconnect allowsto handle the heterogeneity of communications. We present the rationale for choos-ing RF over optics and 3D, the detailed architecture of the network and the chipimplementing it, the evaluation of its feasibility and its performances. During theevaluation phase we were able to show that for a CMP of 1 024 tiles, our solutionallowed a performance gain of 13 %. One advantage of this RF interconnect is theability to broadcast without additional cost compared to point-to-point communi-cations, opening new perspectives in terms of cache coherence.
