摘要 提出一种基于虚拟输出队列的新型NoC架构,采用虚拟输出队列技术解决传统环形架构中存在的死锁和队头阻塞问题。通过改变环数、发包速率和Buff深度对系统进行性能评估,并与2DMesh进行比较。实验结果表明,当节点数为16时,Buff深度为2个～4个flit大小的新型双环NoC架构性能较好。 This paper presents a new NoC architecture. By adopting the virtual outpuLqueue technology, this architecture completely resolves head of line blocking and deadlock which exists in traditional ring topology architecture. By changing ring number, flit sending speed and Buff depth, it evaluates the performance of this architecture and compares with 2D Mesh in the experiment. When node number is 16, the performance of new bidirectional ring topology NoC architecture whose Buff depth is 2~4 flits is better.
