中文摘要：
在分析片上网络通讯功耗与通讯流量的关系模型的基础上,针对片上网络设计中的映射问题,提出了一种新的降低通讯功耗的映射方法,该方法首先对映射过程做预处理,划分成若干候选图,将通讯量大的IP核映射到与其他资源节点距离较短的位置上,利用预处理的结果产生初始解,结合流量估算技术对映射空间动态搜索,从而实现将通讯任务图中的IP核映射到NoC结构图的资源节点上.实验结果表明该方法能有效地降低NoC的通讯流量,从而更加适合求解片上网络的低功耗映射问题.
英文摘要：
A low power mapping method was proposed in this paper for NoC mapping problem based on analyzing the rela-tionship between communication power and communication flow. In order to low down the communication flow of NoC, the proposed method first uses approximated pre-mapping, which maps the larger communication flow IP core to the position close to other vertexes. In mapping step we use the result of pre-mapping step to search better solutions, which fulfills the mapping process from IP core in communication task graph to resource vertex in NoC architecture graph. Experimental results show that communication flow is decreased and it is effective to solve mapping problem with low power.
