To provide efficient, high-performance routing algorithms, a holistic approach should be taken. The key aspects of routing algorithm design include adaptivity, path selection strategy, VC allocation, isolation, and hardware implementation cost; these design aspects are not independent. The key contribution of this work lies in the design of a novel selection strategy, Destination-Based Selection Strategy...
In this paper, we propose an adaptive routing algorithm based on fuzzy logic in which each link cost is dynamically determined based on the current network condition. Using this algorithm, the traffic is distributed through the nodes that are less congested or have a spare capacity. The technique using a fuzzy controller takes advantage of two factors that are the number of empty spaces in the buffer...
In a Multi-Processor System-on-Chip (MPSoC)-based embedded system with Network-on-chip (NoC) as the communication architecture, routing of the communication traffic among the Processing Elements (PEs) contributes significantly to the overall latency, throughput and energy consumption. Design of an efficient routing algorithm for NoC requires a thorough understanding of the role of individual components...
As nanotechnology scales down, the reliability issues are becoming more crucial, especially for Network-on-Chip (NoC) which must provide the communication requirements of Multi-Processor System-on-Chip (MP-SoC) even in presence of faults. In this paper we present a low cost faulty-link-tolerant routing algorithm through dynamic reconfiguration when the regular mesh topology is altered by faulty links...
