A Wireless Network-on-Chip Design for Multicore Platforms

Aggressive scaling of transistors allows integration of hundreds of processors on a chip. However, on-chip interconnects carrying signals between different blocks will be the bottleneck for system performance and reliability. To tackle this problem, the authors developed an on-chip communication infrastructure based on a network-on-chip architecture and developed a hybrid mechanism to transfer data among IP cores by taking advantages of both wired and wireless communications. By using on-chip antennas, one can provide on-chip wireless communication to transfer data across long distances and minimize transfer latency and energy dissipation accordingly.
