چکیده

Monitoring services are essential for advanced, reliable NoC systems. They should support traffic management, system reconfiguration and fault detection to enable optimal performance and reliability of the system. The paper presents a thorough description of NoC monitoring structures and studies earlier works. A distributed monitoring structure is proposed and compared against the structures presented in previous works. The proposed distributed network monitoring system does not require centralized control, is fully scalable and does not cause significant traffic overhead to the network. The distributed structure is in line with the scalability and flexibility of the NoC paradigm. The paper studies the monitoring structure features and analyzes traffic overhead, monitoring data diffusion, cost and performance. The advantages of distributed monitoring are found evident and the limitations of the structure are discussed. DOI: 10.4018/978-1-4666-2776-5.ch008

Reliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)

Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...

Design of a Low-Latency Router Based on Virtual Output Queuing and Bypass Channels for Wireless Network-on-Chip

Wireless network-on-chip (WiNoC) is considered as a novel approach for designing future multi-core systems. In WiNoCs, wireless routers (WRs) utilize high-bandwidth wireless links to reduce the transmission delay between the long distance nodes. When the network traffic loads increase, a large number of packets will be sent into the wired and wireless links and can...
