摘要
Wireless channel-on-chip networks face serious reliability challenges, and the fault-tolerant design of wireless routers has a significant impact on the transmission efficiency of the overall on-chip network. Due to the continuous shrinking of CMOS technology and the integration of wireless technology in complex circuits, WR faults appear to become more prevalent. In this paper, we propose a dynamic detection strategy for wireless interface faults in WiNoC, which classifies the fault scenarios of wireless interfaces in wireless routers, implements wireless interface fault detection in WiNoC operation, and updates the fault scenarios. Meanwhlie, a fault-free WR table-based nearest route algorithm is also presented to maximize the network performance. The Experiments show that the proposed scheme can effectively guarantee the network performance when WR faults occur in the network and is also effective in the case of moderate WR fault rate.
