摘要

在非密集计算任务下，分布式路由片上网络表现出良好的性能.然而当片上网络布局密度接近1时，受算法制约，高链路拥塞率会严重降低分布式路由网络执行大批量数据传输任务的性能.考虑到片上网络需传输数据的密集/非密集特征，由此设计集成有可定向传输事务的混合式路由，通过配置路由节点分配两种路由策略的权限，在片上网络中构建点对点高权限专用数据链路，避免分布式路由自寻链路带来网络长时拥塞、事务处理迟延问题，保证事务并行度，提高网络节点挂载计算核布局的容忍度.同时论文在8×8Mesh结构下对集成有混合路由网络性能进行了测试，结果表明采用混合路由有效提高了传输带宽和链路成功率等网络性能指标.

Abstract

Under non-intensive computing tasks

NoCbasedon distributed routing shows good performance. However

when performing intensive and complex computing tasks

distributed routing lacks of complex high-performance algorithms and link congestion has to be meeting. Especially when the network layout density is close to 1

with high-volume data transmission

a high link congestion rate will seriously degrade the overall performance of the NoC. Considering the variety of the data size transmission on the NoC (dense/non-dense)

designing and encapsulating the lumped routing of reconfigurable directional transport transactions

setting the routing node port

setting the port detection mechanism to assign two routing strategies.At the same time

the performance of 8×8 Mesh of hybrid routing network show that hybrid routing can improve transmission bandwidth and link success rate effectively.
