| Many-Core System-on-Chip (MCSoC) designs are rapidly emerging, which allow superior performance gains while side-stepping the power and heat dissipation limitations of clock frequency scaling. The main advantage lies in the exploitation of parallelism, distributively and massively. Consequently, the on-chip communication fabric becomes the performance determinant. In the meantime, the introduction of Ultra-Wide-Band (UWB) interconnect brings in the new opportunity for tera bps communication bandwidth, milliwalts communication power, and low cost implementation for micron-meter range on-chip communication for future processor generations. In this work, we study the feasibility and applicability of using ultra-short wireless links for multi-hop communication. From architecture to the communication protocol design, we provide the comprehensive designs to deliver an efficient communication architecture for MCSoC. With extensive simulations, the presented work proves that Wireless Network-on-Chip (WiNoC) is a plausible communication infrastructure, which meets the high-performance communication requirements of MCSoC applications. The explorations on the wireless infrastructure and prototype architecture pave the way to a new on-chip communication paradigm. |
