Abstract: Instruction Set Simulator(ISS) and its application in processor modeling and verification are introduced. The modeling methods of Instruction Set Architecture(ISA) and Micro-Architecture(MA) are discussed. Furthermore, the implementation of instruction accurate and cycle accurate instruction set simulator are also investigated. Multithreading technology is used in integration of debugger with ISS. Application of ISS in development of a cipher specific processor is presented.

Key words: Instruction Set Simulator(ISS), processor modeling, instruction accurate, cycle accurate, pipeline processor
