It is difficult to be optimized of routing and arbitration algorithm and be assessed of performance in the beginning of design because of its complex test cases. This paper constructs a scalable and monitored system level model with SystemC for NoC with Packet Connected Circuit (PCC) protocol. The overall performance and transfer details can be evaluated particularly by running the model, and the statistical basis can also be provided to the optimization of designing NoC.展开更多

The orientation-dependent deformation mechanism of the residual grains was also discussed using Schmid factor difference ratio(SFDR) analysis. The results show that the deformed microstructure features typical "necklace" structures. Many distorted twin boundaries can be observed within the residual grains at 950 ℃. When the deformation temperature increases to 1150 ℃, the volume fraction of dynamic recrystallization(DRX) increases, leading to the extensive formation of primary Σ3 twin boundaries.

The maximum GND density value can be obtained at the interface of "soft–hard" grains. The GND density also increases at higher strain rates, and the number of DRX grains significantly affects the distribution of the GND density. Moreover, based on the calculations and SFDR analysis, it can be summarized that the {100} and {111} grains are prone to deform in the uniserial slip mode and the multiple slip mode, respectively.展开更多
