SYSTEM AND METHODS PROVIDING RUNTIME BYTE CODE SIMPLIFICATION FOR PLATFORM INDEPENDENT LANGUAGES

摘要

Methods and devices are provided which transform a sequence of instructions of a platform independent instruction set, such as the Java instruction set for example, by defining a group of functionally equivalent instructions in the instruction set and defining a substitution instruction, and by substituting the substitution instruction for each occurrence in the sequence of instructions of one of the predetermined group of functionally equivalent instructions. The methods are extendable to perform substitutions for multiple groups of functionally equivalent byte codes. Also provided is a method of replacing multi-byte instructions with single-byte instructions.
