Inventors: Min Wu, Ashwin Swaminathan, Yinian Mao
The present invention advantageously applies information hiding techniques to program binaries of fixed-width instruction set processors, whereby extra information is transparently embedded. The supplemental information can be extracted by the processor at very low cost in a manner that supplements computer system functionality. The invention stores and extracts the additional information in computer programs in an ISA-independent way and without inserting extra instructions. The embedded data may be used in a variety of ways, such as for value and branch prediction in pipelined instruction execution, as well as to validate the integrity and origin of a program in trusted computing environments.
