Communication energy constrained spare core on NoC

Abstract

In Multi-processor System on-chip, each processor produce and consumes high data. Transporting of data is a crucial role in MPSOC, Therefore Network on Chip (NoC) preferred as a communication medium, because good communication performance and fast operating. While considering NoC Architectural some temporary, permanent faults occur in the core. This paper propose the placement of spare core and its communication energy constraints, we investigated energy metrics in place of spare core and finally saving communication energy leads to previous algorithms.
