The present invention discloses method and system for a multimode simulator having an emulation core with improved performance. In an embodiment of the invention, the overhead caused by the exclusive use of the simulation technique using one instruction-at-a-time interpretation is reduced by additionally using binary translation for executed blocks of interpreted instructions (i.e. that contain no jumps out of the block) from the same instruction set architecture description. Since performing translations too frequently can undesirably increase overhead by overloading the cache, the binary translation is only performed for blocks that are executed frequently. Once the blocks are translated e.g. by forming the block from instructions via templates and generating the collective code, the overall simulator performance is significantly improved by running the blocks instead of running the instructions one-at-a-time.

Average flowing-through time is an important scheduling index to which enterprises pay attention. When a dispatching method based on soft computing and the like is used for optimizing dispatch, global simulation is required to be carried out on a dispatching strategy to obtain a corresponding average flowing-through time index; the process needs to be carried out several times; the process consumes longer time if used for building an accurate simulation model for a whole larger scale production line as well as used for global simulation on the dispatching strategy; thus, quick prediction of the average flowing-through time index has the important meaning for improving the performance of the dispatching algorithm. The invention discloses a quick prediction method of average flowing-through time on basis of index compensation, which divides a machine group into a bottleneck machine group and a non-bottleneck machine group so as to loosen the working capability of the non-bottleneck machine group to build a simplified dispatching model; then, an SVM (support vector machine) is used for obtaining the compensation relationship between the corresponding average flowing-through time indexes of the simplified dispatching model and a non-simplified dispatching model, thus realizing the quick prediction of the average flowing-through time index.
