| 摘要: |
| 针对路由器中的交叉开关分配，提出面向网络延迟均衡性的分配策略，旨在通过更加公平的交叉开关分配策略提升网络延迟均衡性，从而进一步提升系统性能。通过在全系统模拟器上运行SPEC CPU2006实验表明，与传统的分离式分配策略和最新的TS-Router分配策略相比，延迟标准差分别平均降低了13.8%和3.9%，而最大延迟分别平均降低了45.6%和15.1%。在系统性能方面，相比于TS-Router，所提分配策略在IPC上平均提升了0.8%。在分离式分配器的基础上完成了硬件实现，并给出了速度、面积和功耗方面的开销评估。 |

| Abstract: |
| According to the problem of switch allocation, a network latency equalization-oriented switch allocation strategy was proposed to improve system performance by designing a more fairness switch allocation strategy and improving the degree of network latency equalization. The evaluation of the design with SPEC CPU2006 benchmarks was performed in a full-system simulator. Compared with the canonical separable switch allocator and the TS-Router (recently proposed switch allocator), the experiments show that the approach decreases LSD (latency standard deviation) by 13.8% and 3.9% respectively, as well as ML (maximum latency) by 45.6% and 15.1% respectively. The approach improves system throughput by 0.8% over that of TS-Router. Finally, the design is implemented based on the separable switch allocator, and it can perform the evaluation in speed, area and power. |
