Abstract

Project in brief: reconfiguring the network according to application which has been run on the network is one of the ways to improve using resources in the network-on-chip. There is a hierarchical cluster based NOC. In this network, nodes are going to partition into clusters. Every cluster’s node can have its own configuration and the configuration of inside of each cluster is unchangeable however the relationship between clusters is configurable. This ability is made by some switches which are located between clusters and they can change the way that clusters are related. The number of nodes which is inside the cluster are cluster size and the number of switches between two adjacent...

Abstract

In recent years, confrontation with hardware Trojans has become a major concern due to various reasons including outsourcing. Such a growing threat is more pronounced in reconfigurable devices as they are used in widespread applications due to low design cost and short time-to-market. Besides their vulnerability to hardware Trojan attacks, SRAM-based reconfigurable devices are also significantly susceptible to faults originated by particle strikes. There have been various methods to mitigate either hardware Trojan attacks or faults. To our knowledge, however, no method has been presented that can integrate detecting, distinguishing, and mitigating faults and Trojans. In this paper, we...

Power- and performance-efficient cluster-based network-on-chip with reconfigurable topology

Abstract

Topology is widely known as the most important characteristic of networks-on-chip (NoC), since it highly affects overall network performance, cost, and power consumption. In this paper, we propose a reconfigurable architecture and design flow for NoCs on which a customized topology for any target application can be implemented. In this structure, the nodes are grouped into some clusters interconnected by a reconfigurable communication infrastructure. The nodes inside a cluster are connected by a mesh to benefit from the interesting characteristics of the mesh topology, i.e. regular structure and efficient handling of local traffic. A reconfigurable inter-cluster topology then eliminates the...
