    摘要： In a host system, a method for using instruction scheduling to efficiently emulate the operation of a target computing syste includes preparing, on the host system, an instruction sequence to interpret an instruction written for execution on the target computing system. An instruction scheduling on the instruction sequence is performed, to achieve an efficient instruction level parallelism, for the host system. A separate and independent instruction sequence is inserted, which, when executed simultaneously with the instruction sequence, performs to copy to a separate location a minimum instruction sequence necessary to execute an intent of an interpreted target instruction, the interpreted target instruction being a translation; and modifies the interpreter code such that a next interpretation of the target instruction results in execution of the translated version, thereby removing execution of interpreter overhead.
