Abstract: This paper presents a new ring topology Network-on-Chip(NoC) architecture. By improving the input port virtual channel, the architecture completely prevents Head of Line blocking(HoL) and deadlock with one pipeline stage in a like Virtual output Queue(VoQ) way, without consuming too much resource. This paper evaluates the performance of this architecture under some different parameters. Compared with CELL EIB ring implementations, its packet minimum latency is only 11 cycles, while the maximum throughput is 25.6 Gb/s.

Key words: ring topology, wormhole routing, virtual channel, Head of Line blocking(HoL)

摘要： 提出一种基于虫洞路由的无HoL阻塞环形片上互联网络架构，实现了在不消耗太多资源的前提下，用一级流水线以类虚拟输出队列的方式完全消除队头阻塞和死锁。评估不同参数下该环形架构的性能，与CELL EIB等环形实现相比，该架构以单数据包仅11周期最小延时的性能明显优于其他环形架构，同时最大吞吐率达到25.6 Gb/s。
