| 摘要: |
| 近年来，无缓冲路由器由于不需要缓冲器而成为片上网络低开销的解决方案。为了提高无缓冲路由器的性能，提出一种单周期高性能无缓冲片上网络路由器。该路由器使用一个简单的置换网络替换串行化的交换分配器与交叉开关以实现高性能。虚通道路由器与基准无缓冲路由器相比，该路由器在TSMC 65nm工艺下可以以较小的面积开销达到2GHz的时钟频率。在合成通信负载与真实应用负载下的模拟结果表明，该路由器的包平均延迟远小于虚通道路由器和其他无缓冲路由器。 |

| Abstract: |
| Recently, bufferless router, which does not need buffers, has become a low-cost solution for Network-on-Chip. To improve the performance of the bufferless router, a 1-cycle high-performance bufferless router was proposed for Network-on-Chip. The router used a simple permutation network instead of the serialized switch allocator and the crossbar to achieve high performance. Compared with the virtual channel router and the baseline bufferless router, the proposed bufferless router can achieve the frequency of 2GHz with small area cost under TSMC 65nm technology. Simulation results under both synthetic and application workloads demonstrate that the proposed bufferless router achieves much less average packet latency than the virtual channel router and other bufferless routers. |
