Multi-application Specified Link Removal Strategy for Network on Chip

To benefit of both regular topology and partially customized structure, we adopt application specified link removal strategy to minimize NoC (Network on Chip) area consumption with partial regularity twist and guaranteed performance. Our link removal for single application mainly includes iterative link removal selection algorithm based on low link utilization for topology optimization and turn model based deadlock free routing algorithm for irregular 2D Mesh with reduced links. In addition, we also consider multiapplication from realistic requirement and try to define various execution modes. The seamless combination of multiapplications and link removal method is achieved via corresponding interoperation of removed link set. Taking typical media applications VOPD and MWD for example, the simulation results verify proposed multi-application specified NoC link removal strategy valid for area cost optimization and acceptable performance degradation.
