Shuffle Exchange Diagonal Mesh Interconnection Network
The Shuffle Exchange Diagonal Mesh (SEDM) interconnection network uses the properties of the mesh, diagonal links and the shuffle-exchange to form a hybrid interconnection network in place to enhance the efficiency of communication in parallel computing systems. SEDM enhances performance by reducing network diameter and average path length and as a result decreases communication latency and increases fault tolerance. Its architecture is consistent and exhibits a regular structure that is suitable to VLSI implementation and it scales. Fault resilience and flexibility of data routing is enhanced by the inclusion of diagonal links and shuffle links thus liberating the topology when compared with conventional mesh and shuffle-exchange networks. Applications that depend on reliable and quick inter-processor communications gain a lot using this design. A de facto prospective design to nextgeneration multiprocessor systems is SEDM as it poses a reasonable compromise between complexity, performance and cost.
