An SoC is modeled as a set of pre-designed cores characterized by their area and interfaces and a set of end-to-end communication requirements on the channels connecting them. These requirements are the input specification to a synthesis process that produces an on-chip communication (OCC) by assembling components such as interfaces, routers, buses and links, from a target library. Models for functionality, cost, and performance of each element are captured in the library together with their composition rules. Our contributions is two pronged: 1) A methodology for the design of OCC based on: -a mathematical framework to model communication at different levels of abstraction from the point-to-point input specification to the library elements and the final implementation; -the formulation of an optimization problem and a heuristic synthesis algorithms to solve it: given a set of communication requirements on the throughput and latency of the channels it returns a communication implementation that satisfies them while minimizing power consumption. 2) A publicly available software package that includes alternative synthesis algorithms, various communication libraries, supporting tools for simulation and visualization, and a collection of SoC benchmarks.
