Abstract: The present disclosure provides a vector graphics data processing method, system, medium, and vector graphics processing device. The method includes the following operations: building a vector primitive path intersection data structure (PIDS) based on coordinates of path intersections (PIs); when a new PI is generated, comparing information of the new PI to information of existing PIs corresponding to an X coordinate or Y coordinate of the new PI; and storing the information of the new PI at a corresponding position in the PIDS corresponding to the X coordinate or Y coordinate of the new PI based on a result of the comparing. Only effective PI data are saved, thereby reducing memory footprint and memory bandwidth, and improving vector graphics processing performance.

Abstract: The present disclosure provides a cooperative access method, system, and architecture of an external storage.
