智能终端中热IP核的通信方法

[摘要] 片上网络通信架构的改进，使热IP核连接多个路由器，并且原本与热IP核相连的一个路由器的通信量被分配到多个路由器上。基于改进的片上网络通信架构，又设计出新的路由器选择算法。在该算法中，可以根据热IP连接的路由器的当前状态选择数据通信的路由，这样使得热IP能够更加均匀地分配通信量，从而有效地提高了数据传输效率，降低数据传输延时。实验表明，新的算法能够有效减少传输延迟。

[Abstract] In this paper, we describe improvements to the communication architecture of network-on-chip. Our proposed method involves connecting the hot IP core to more than one router. Traffic is distributed to routers that connect to the hot IP core. We also design a router-selection algorithm based on this improved communication architecture. A router is selected for communication according to the statuses of routers connecting to the hot IP core. This allows traffic be evenly distributed to routers. Our experimental results show that this method reduces transmission delay.
