摘要： Network-on-Chip (NoC) is an oncoming solution to the communication bottleneck of System-on-Chip (SoC). For a good design, it runs a simulation verification before the design is realized. The key factors to the accuracy and simulation speed of a simulator depend on how the simulator abstracts the NoC design. The present invention provides an object-oriented NoC modeling, which divides the NoC design space into many design blocks and models them into many abstraction levels. The present invention defines these models carefully to obtain good hardware accuracy. The present invention also provides an object implementation library of different abstraction levels. Thereby, the present invention can reduce the coding time via selecting required components from the object implementation library, inheriting them with some modifications or using them directly. The present invention extends the design exploration space of NoC, preserves good hardware characteristics, and significantly reduces coding effort of a new NoC design.

摘要： Network-on-Chip (NoC) is to solve the performance bottleneck of communication in System-on-Chip, and the performance of the NoC significantly depends on the application traffic. The present invention establishes a system framework across multiple layers, and defines the interface function behaviors and the traffic patterns of layers. The present invention provides an application modeling in which the task-graph of parallel applications is described in a text method, called Parallel Application Communication Mechanism Description Format. The present invention further provides a system level NoC simulation framework, called NoC-centric System Exploration Platform, which defines the service spaces of layers in order to separate the traffic patterns and enable the independent designs of layers. Accordingly, the present invention can simulate a new design without modifying the framework of simulator or interface designs. Therefore, the present invention increases the design spaces of NoC simulators, and provides a modeling to evaluate the performance of NoC.
