The book provides state-of-the-art methods to solve some of the most important problems encountered during NoC design. It is the first book to present in depth the state-of-the-art algorithms and optimization models for performing system-level design of NoCs.
Developing NoC based interconnect tailored to a particular application domain, satisfying the application performance constraints with minimum power-area overhead is a major challenge. With technology scaling, as the geometries of on-chip devices reach the physical limits of operation, another important design challenge for NoCs will be to provide dynamic (run-time) support against permanent and intermittent faults that can occur in the system. The purpose of Designing Reliable and Efficient Networks on Chips is to provide state-of-the-art methods to solve some of the most important and time-intensive problems encountered during NoC design.
