Design of Interconnection Networks

Digital systems of all types are rapidly becoming communication limited. Movement of data, not arithmetic or control logic, is the factor limiting cost, performance, size, and power in these systems. Historically used only in high-end supercomputers and telecom switches, interconnection networks are now found in systems of all sizes and all types - from large supercomputers to small embedded systems-on-a-chip (SoC) and from inter-processor networks to router fabrics. Indeed, as system complexity and integration continues to increase, many designers are finding it more efficient to route packets, not wires.
