Abstract
A system and method for executing CISC instructions in a RISC environment are disclosed. A mapper/interface circuit receives CISC instructions which can be from an x86 instruction set, translates them into compatible RISC instructions and forwards them to a RISC microprocessor for execution. The interface circuit is separate from the RISC microprocessor resulting in off-chip hardware translation which improves microprocessor efficiency and simplifies processor and hardware development. The instructions can be translated in groups which are defined by boundaries in the CISC instructions. One group of instructions can be forwarded to the microprocessor for execution while a subsequent group is simultaneously translated. The plug-in mapper/interface circuitry of the invention is plug compatible with an x86 processor such that the circuitry of the invention can be plugged into a standard x86 socket in a standard x86 mother board. Since standard commercially available components can be used as the host, considerable cost savings in system development and manufacture are realized.
