1. A method of simulating an instruction set architecture (ISA) with a instruction set simulator (ISS), comprising:

  • fetching a first decoded instruction during a run time, wherein the decoded instruction is decoded from an original instruction in a target application program during a compile time preceding the run time, the decoded instruction pointing to a template configured to implement the functionality of the instruction;
