Processor overhead is reduced and processor performance, particularly processing speed and power savings, is improved, allowing real-time processor restarts, by skipping operational codes (opcodes) singly or in groups in accordance with one or more execution bits set during post-processing in opcodes preceding opcodes to be skipped. Thus portions of an application program which consume excessive power or are unsupported in particular operating environments can be easily and selectively de-activate while maintaining the integrity of the applications program. Local or cache memory is also effectively expanded and processor performance improved by eliminating opcodes from local or cache memory which will not be called.
