|Applicants:||PAX COMPUTER TECHNOLOGY(SHENZHEN)CO., LTD
|Title:||METHOD AND DEVICE FOR APPLICATION PROGRAM RUNNING ACROSS SYSTEMS|
A method and a device for an application program running across systems. The method comprises: loading a target application program (202); applying the current operating system for a memory space for the target application program (204); according to the address of the applied memory space, modifying the global variable address and the absolute jump instruction address of the target application program, to adapt to the memory space of the current operating system (206); acquiring a software instruction (SWI) of the target application program (208); redirecting the SWI instruction to an instruction for calling the current operating system (210). The method enables a target application program to run across systems without the need for modifying the source code of the target application program, greatly simplifying the operation of the application program running across- systems.
