System and method of transfer of control between memory locations

摘要

Disclosed are a system and a method for controlling execution of a program. An example method includes determining a memory sector of interest in a first virtual memory location; duplicating the memory sector of interest in a second virtual memory location; tagging the memory sector of interest in the first virtual address space and the duplicated memory sector in the second virtual address space with different tags; selecting between the memory sector of interest and the duplicated memory sector a memory location for execution of the program; executing, by a hardware processor, the program in the selected memory location until receipt of a notification to transfer execution of the program from a memory sector tagged with one tag to a memory sector tagged with a different tag; and transferring program execution to the memory location other than the one in which the notification was received.
