This paper proposes a hybrid communication medium for on-chip communication targeting adaptive SoC architectures. Unlike the work carried out in literature, where the term ?hybrid? is used for the existence of more then one topologies for communication, the novelty of the proposed medium lies in combining two different communication media. In this paper, global bus and crossbars co-exist in an SoC. RFID Tag Reader is used as the targeted application and bus based system and crossbars based system implementation has been used for comparison purposes. RTL level implementation of the proposed communication structure is carried out for accurate power and area calculations. Results have demonstrated the effectiveness of hybrid communication medium over traditional bus and crossbars based SoC.
