Abstract

A method, for use in a processor context, wherein instructions in a program executable are encoded with plural instruction set encodings. A method wherein a control instruction encoded with an instruction set encoding contains information about decoding of an instruction that is encoded with another instruction set encoding scheme. A method wherein instruction set encodings are randomly generated at compile time. A processor framework wherein an instruction is decoded during execution with the help of information provided by a previously decoded control instruction.
