Communication energy constrained spare core on NoC

In multi-processor system on-chip, each processor produces and consumes high data. Hence, transporting of data becomes crucial in MPSOC. Therefore, Network on Chip (NoC) is preferred as an alternate medium because it provides good communication performance with comprehensive fast operation. This paper proposes the placement of spare core and its communication energy constraints while considering temporary and permanent fault occurrences in the core. We investigated energy metrics instead of spare core, bringing up lots of saving in terms of communication energy over the previous algorithms.
