| 摘 要： | 提出了一种新的基于NoC(Network on Chip)的不规则IP模块映射方法.其基本思想是把较大的IP模块分解成几个小的IP虚模型,或把几个较小的IP模块组合成一个IP虚模型,使得每个IP虚模型能映射到NoC结构的一个资源节点上.通过计算曼哈顿距离和输入/输出度,可以确定每个通信节点中缓冲区的大小.根据计算的通信代价可以对初始映射结果进行调整,从而可以避免通信拥塞,降低系统的功耗.

| Abstract: | A NoC based irregular IP mapping algorithm is showed in this paper.The basic idea is to decompose a large IP core into several dummy IPs or integrate several small IPs into one dummy IP,such that each dummy IP can fit into one single tile.The size of buffer in every communication node can be decided by computing the Manhattan distance and I/O degree.The initial mapping result can be adjusted according to the communication cost,and thus can avoid communication congestion and reduce the power consumption. |
