一种新型NoC拓扑结构的研究

提出一种片上网络(NoC)拓扑结构--Spidemet,并对其网络的主要属性如节点度、网络直径、连通度、平均最短路径和平均最短布线等进行了研究.首先将Spidemet与其它拓扑结构的属性进行比较,并采用模拟退火的布局映射算法,根据 NoC 的布局结构,将不同的节点放入 NoC 网格中,即给出一组被绑定和调度的可供选择IP核,在满足IP核所占用芯片面积的条件下将选择的IP核映射到网络中,目标是最小化平均布线长度.网络拓扑结构图描述文件和IP核任务图作为输入.实验中运行基准程序,结果表明提出的网络拓扑结构更适合于将来的 SoC 的片上网络构造.

A new topology for system-on-chip design

This paper proposes a topology structure for network-on-chip (NoC),and compares it with other topology networks in terms of five kinds of mainly properties:node degree,network diameter,connectivity,the average shortest circuit path,and the average shortest wire length.A simulated annealing algorithm is applied to embedment of different nodes onto different tiles on a grid NoC platform that act as placeholders in the architecture.Precisely,given an application de- scribed by a set of concurrent tasks,already...
