A Unified Error Control Coding Scheme to Enhance the Reliability of a Hybrid Wireless Network-on-Chip

Hybrid wireless Network-on-Chip (NoC) has emerged as an alternative to the traditional multi-hop wire line NoC to achieve higher performance and low energy dissipation in on-chip data transfer. However, introduction of on-chip wireless links lowers the overall reliability of the data communication fabric. In this paper we propose a unified Error Control Coding (ECC) mechanism which can be effectively used to restore the reliability of a Wireless NoC (WiNoC). We demonstrate that with carefully designed ECC schemes in the WiNoC it is possible to achieve high gains in performance due to the wireless links while maintaining comparable reliability as that of a traditional wire line NoC.
