Low cost fault-tolerant routing algorithm for Networks-on-Chip

摘要

A novel adaptive routing algorithm - Efficient Dynamic Adaptive Routing (EDAR) is proposed to provide a fault-tolerant capability for Networks-on-Chip (NoC) via an efficient routing path selection mechanism. It is based on a weighted path selection strategy, which exploits the status of real-time NoC traffic made available via monitor modules. The key performance goal is to maintain throughput under congested and faulty conditions via effective routing path decisions. In the proposed EDAR, port
