In computer science, an instruction set architecture (ISA), also called computer architecture, is an abstract model of a computer.Instruction set virtualization is a processor virtualization technique that enables emulation of the instruction set of one processor on a different processor. models are defined at the ISA level, they therefore apply both to system and application software. creating an additional layer between the software stack Instruction Set Architecture based Virtualization. ISA-based virtualization is implemented in software, and it usually emulates the ISA in software where it
