    • In this system, program data is generated by configuring a plurality of modules based on a relationship between dependence of the modules composing the program. Then, generated two versions of program data is compared starting from a head address of each of the program data, and data at an address, and thereafter, where the data first makes a difference is extracted to generate difference data. Further, a center holds the latest version of program and at least one item of difference data, and transmits the whole data of program or difference data corresponding to a program version in a terminal apparatus, and the program is updated in the terminal apparatus using the received data.

    • An arithmetic unit includes a switching device 16 and a cache controller 19. The switching device 16 determines whether desired data to be read by the CPU 11 is in a RAM 14, and allows, depending on a result of the determination, the CPU 11 to directly read the desired data from a ROM 13. The cache controller 19 controls a cache 12 so that the RAM 14 is initialized based on cache data corresponding to the desired data stored in the cache 12. In an arithmetic unit having a CPU, a cache, RAM, and ROM configured in the above manner, the time required for a startup process is reduced.
