Abstract: A patching device and method thereof for patching a firmware function by a patch function. When a fetch address from a processor does not correspond to the firmware function, the patching device outputs an instruction of the fetch address to respond to the processor. When the fetch address corresponds to the replaced firmware function, the patching device outputs an artificial instruction to respond to the processor. The artificial instruction is one of series of machine codes corresponding to a plurality of patch intermediary instructions utilized to direct the processor to jump to the beginning address of the patch function.
