Application-Aware Generation and Optimization for NoC Topology

In this paper, we present a methodology for modeling, analysis and generation of NoC topology. Specially, our optimization framework of static and dynamic properties ensures core-to-core communication of the complete network. Our approach 1) fully exploits the regularity of standard topology and the flexibility of application-specific topology 2) generates a scalable network containing heterogeneous topologies, which raises the abstraction level of reuse from resources to subnets 3) satisfies NoC application. We evaluate and compare the performance of the topology generated utilizing our methodology with regular NoC topologies. Experimental results show the proposed design flow is efficient to provide superior performance for predefined requirements, and minimal cost function is achieved. In addition, we applied several multimedia applications as case studies.
