Method and apparatus for hardware assisted control redirection of original computer code to transformed code

摘要

One embodiment of the present invention provides a system that redirects control flow of original code to transformed code. The system includes a computer processor with an instruction fetch unit that determines a next instruction to be executed by the processor. The system also includes a control redirection buffer, which indicates whether to conditionally redirect execution from a first instruction address to a second instruction address so that the transformed code at the second instruction address can be executed in place of the original code at the first instruction address.
