Abstract

One of the benefits of wireless inductive through chip interface is that it allows to build a shared bus just by placing a coil on the same location in each chip. Since providing dedicated channels for arbitration is expensive, carrier sense multiple access with collision detection (CSMA/CD) is hopeful as the bus control method. Here, a rotationpersistent collision avoidance algorithm dedicated for the wireless inter-chip bus is proposed. In the method, after the carrier sense, only a specific chip can instantly send the data, and others must wait for a random time interval. It improved the throughput of 1-persistent CSMA/CD by 33% on average.
