Summary:The invention discloses a method for decreasing sizes of multicore firmware. The method comprises a repeated segment information collection step: analyzing an initial address and a length of a sharedspace in single-core firmware through analyzing a file structure of a firmware file, determining repeated segment information and forming a configuration file; and a firmware generation and combination step: before combining a plurality of pieces of single-core firmware, preferentially reading configuration information, obtaining initial addresses and lengths of repeated segments, during the combination of multi-core firmware, obtaining information of the repeated segments, for repeated fields of all the cores, only retaining the information of the repeated field in the first single-core firmware, and discarding data, falling in the repeated field, of the other single-core firmware. According to the method, the storage of repeated samples is avoided, the sizes of the combined firmware aredecreased, the problem tha
