13.5. The Three NoC Temptations

Dr. Se-Joong Lee of KAIST (Korea Advanced Institute of Science and Technology) discusses what he calls the three NoC temptations. The first such temptation is the siren song of the mesh network. With their elegant, regular architectures; good scalability; and opportunities for exploring adaptive routing algorithms, mesh networks have become the darlings of academic NoC research. However, Lee argues, mesh networks aren’t that attractive under close scrutiny. They are inefficient for global (broadcast) transactions and they are not nearly so regular and orderly as they appear in published academic articles. When actually laid out on silicon, mesh networks complicate the physical layout of the SOC and they require ...
