Abstract

The present invention is a method and system for accessing at least one emulated readable storage in a processor-based system. The system comprises a memory for storing instruction sequences by which the processor-based system is processed. The memory has at least one readable emulated storage location. A processor is coupled to the memory, and the stored instruction sequences cause the processor to (a) detect an access to at least one readable storage element; (b) transfer the access to the at least one readable storage element to an access to the at least one readable emulated storage location; and (c) process an instruction sequence corresponding to the access to the at least one readable storage element. The invention also relates to a computer system and method for transferring information.
