A NoC-Based High Performance Deadlock Avoidance Routing Algorithm
Zhaohui Song, Guangsheng Ma, Dalei Song · 2008
To help optimize Network-on-Chip (NoC) communication performance while ensuring deadlock avoidance routing, a high performance deadlock avoidance routing algorithm in routing table based NoC routers is presented, a cycle in channel dependency graph expressing NoCpsilas routing communication can be broken by restricting the routing function of some node while ensuring destination reachability of each communication pair to avoid the deadlock. Performance evaluation is demonstrated that the proposed deadlock avoidance routing algorithm have higher performance.
