Abstract: The present paper firstly improves the existing method for generating self-similar sample traces and gives a data processing and transmitting model - DPaTM of systolic PE. Then, by simulating and surface fitting, it establishes the traffic model called PFTM of 2-input single-frame systolic PE using whittle and wavelet estimator respectively with 1-order, 3-order and 5-order polynomial. Thirdly, it decomposes the NoC design implementation structure and proposes a unified traffic modelling method based on PFTM. The traffic model presented only depends on the characteristics of input traces and can be used in any NoC application-specific design. Finally, the PFTM model is used to test the pipelining and paralleling PEs which are usually adopted in SoC design and implementation. Simulation results show that the method of self-similar traffic modelling-PFTM for NoC is effective and can be used widely.
