In this paper, the authors demonstrate the effect of communication media on significant system characteristics e.g. throughput, power consumption of a reconfigurable WiMAX compliant system on chip. The four communication media considered includes, a standard bus base system, cross bar based system, AMBA bus and their novel hybrid communication (crossbus) system where bus and crossbars co-exist. A case study of a system consisting of a LEON processor, a reconfigurable FFT and a reconfigurable Viterbi decoder is considered with the option of system scalability for future upgrades.
