Abstract

Modern System-on-Chip design uses a rapidly increasing number of processing units for advanced information processing. When moving towards a billion-transistor era, ever increasing complexity and density of embedded components exacerbate on-chip communication, which serves as the fabric to integrate these heterogeneous components and provide a communication mechanism among them. In order to bridge the widening gap between on-chip communication needs and projected SoC performance, we propose a self-configurable multihop wireless micronetwork, dubbed Wireless Network-on-Chip, to serve as on-chip data and control communication infrastructure for next-generation billion-transistor SoCs. We present application-specific system architecture design of WNoC with the focus on radio frequency infrastructure. We propose a synchronized and distributed medium access control protocol for WNoC to resolve contentions between RF nodes. Binary countdown-based contention resolution and hidden terminal elimination schemes increase throughput and network utilization. Our simulation results show that DBC-MAC can achieve a promising performance in terms of throughput, latency, and network configuration.
