A major problem in designing new and more powerful microprocessors is that of establishing a new instruction set that tkes advantage of new technological capabilities. Since most software is written for existing processors, introducing a new instruction set usually severely limits the software base for the new system. A new microprocessor instruction is described which allows the introduction of new instruction sets, yet still allows fast emulation of existing machines.
