摘要： 针对XY-YX算法局部路径选择单一、较容易出现拥塞热点区域、不能很好适应高速的网络数据传输等问题，提出一种无死锁路由算法（dead-lock free XY-YX）.该算法通过改进XY-YX路由算法，达到了减轻局部链路负载过重导致的热点问题的目的；此外，为了适应改进的路由算法，设计了一种无死锁结构的路由，避免了死锁的出现.在本文设计的无死锁路由架构上仿真后，结果表明，改进的路由算法，相比于XY路由算法和XY-YX路由算法，其网络平均延时与吞吐量均有所提升.

关键词: 路由算法, 无死锁路由, 片上网络

Abstract: To solve XY-YX routing algorithm's problem of choosing a single key path, liable to fall into hot spot region and cannot adapt to high speed network data transmission, a modified XY-YX routing algorithm with dead-lock free XY-YX routing is set up. The modified algorithm can release the burden of link circuit. What's more, in order to adapt to the modified algorithm, a dead-lock free route is put forward to avoid the dead-lock. Simulation result shows that the modified routing algorithm, experimented on dead-lock free route, can keep lower level latency and achieve higher network throughput than XY routing algorithm and XY-YX routing algorithm.

Key words: routing algorithm, dead-lock free route, network on chip
