ABSTRACT:
A method and system 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 processor 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 in accordance with the present invention provides increased real-time performance for relatively modern RISC microprocessors.
