Petri net modeling and FPGA implementation of parallel computing

In the analysis of existing methods of Petri net modeling and FPGA implementation of the models, this paper firstly discussed the Petri net modeling of parallel computing. This method included decomposing the parallel computing task into multiple parallel processing units, and modeling the system by using IOPT net. Then it proposed the double layer structure, which contained monitoring layer and of algorithm layer, in order to map the Petri net model to FPGA implementation. This implementation method was an effective solution to the problem that transitions of Petri nets model could only represent the simple addition and subtraction operations. A matrix multiplication application shows that the above methods are correct and generic. Finally, it gave further research directions.
