PROBLEM TO BE SOLVED: To provide an emulation system and method for legacy microprocessor instructions making it possible to improve real-time performance. SOLUTION: The method and system are for emulating instructions of legacy microprocessors which execute a compiled high-ordered language such as C/C ++, in which the compiled code is structured such that data and instructions segments are segregated. In order to improve the real-time performance of the system, legacy instructions are directly mapped to equivalent instructions of the host computer where possible. Additional techniques may optionally be employed to further increase the real-time performance of the system. By utilizing the direct mapping of the legacy instructions to host instructions, the emulation system provides increased real-time performance for relatively modern RISC microprocessors.
