TLM model for GPU geometric primitive start mark management in plane clipping based on SystemC

The invention relates to a TLM model for GPU geometric primitive start mark management in SystemC-based plane clipping, and the model comprises a geometric primitive storage unit which is used for storing a primitive vertex package of a first primitive vertex in a geometric primitive; a primitive command parsing unit which is used for setting a first cutting mark according to a first starting markin the primitive vertex packet; a first primitive clipping unit which is used for judging the relationship between each first line segment in the basic primitives and the cutting plane according to the intersection relationship between the basic primitives formed by the vertexes of the plurality of first primitives and the cutting plane during plane cutting, and then updating the first cutting mark as a second cutting mark or reserving the first cutting mark according to the relationship between each first line segment and the cutting plane; and a primitive output control unit which is used for setting initial mark i
