ABSTRACT:
Systems and methods for efficient processing of virtual hardware memory accesses to using runtime code patching. Virtual hardware memory accesses are processed by handling a program's OS-trapped memory exception and performing runtime patching on the program's code to bypass the OS-trapped memory exception mechanism. Program runtime patching comprises modifying function addresses in a program's function address table to redirect function calls to virtualization functions for processing virtual hardware memory accesses without triggering OS-trapped memory exceptions.
