Security has gained increasing relevance in the development of embedded devices. Towards the aim of a secure system at each level of the design, in this paper we address security aspects related to networks-on-chips (NoCs) architectures. After presenting the attacks most likely to address NoCs, we survey existing academic and industrial secure architectures(More)
Security is gaining relevance in the development of embedded devices. Toward a secure system at each level of design, this paper addresses security aspects related to Network-on-Chip (NoC) architectures, foreseen as the communication infrastructure of next-generation embedded devices. In the context of NoC-based multiprocessor systems, we focus on the(More)
Security issues are emerging to be a basic concern in modern SoC development. Since in the field of on-chip interconnections the security problem continues to remain mostly an unexplored topic, this paper proposes a novel technique for data protection that uses the communication subsystem as basis. The proposed architecture works as a firewall managing the(More)
As CMOS technology scales down into the deep-submicron domain, the aspects of fault tolerance in complex Networks-on-Chip (NoCs) architectures are assuming an increasing relevance. Task remapping is a software based solution for dealing with permanent failures in processing elements in the NoC. In this work, we formulate the optimal task mapping problem for(More)
Networks-on-Chip (NoCs) appeared as a strategy to deal with the communication requirements of complex IP-based System-on-Chips. As the complexity of designs increases and the technology scales down into the deep-submicron domain, the probability of malfunctions and failures in the NoC components increases. This paper focuses on the study and evaluation of(More)

Modern embedded systems increasingly require adaptive run-time management. The system may adapt the mapping of the applications in order to accommodate the current workload conditions, to balance load for efficient resource utilization, to meet quality of service agreements, to avoid thermal hot-spots and to reduce power consumption. As the possibility of(More)
