PROGRAM UPDATING DEVICE, PROGRAM UPDATING METHOD, PROGRAM UPDATING PROGRAM AND PROGRAM UPDATING SYSTEM

摘要

To provide a program updating device, a program updating method, a program updating program, and a program updating system that reduce a size of a work area on a terminal device while suppressing a size of a patch.SOLUTION: A division unit 21a divides, when a write destination of a patch instruction spans a plurality of blocks, the patch instruction so as not to span the plurality of blocks. Then, a grouping unit 21b groups a patch command having a same write destination block. Next, a specifying unit 22a specifies a dependency relationship between the groups, and a resolving unit 22b resolves the dependency relationship between the groups and rearranges the groups.SELECTED DRAWING: Figure 2
