PURPOSE: To evade the overlapping execution of the same arithmetic processing and to execute a high-speed re-calculation processing by reading an arithmetic result corresponding to the arithmetic relation information and defining it as the arithmetic result of the arithmetic processing when the arithmetic relation information of the arithmetic processing to be executed matches with the arithmetic relation information stored in a cache memory. CONSTITUTION: The arithmetic relation information and the arithmetic result of the executed arithmetic processing are stored in the cache memory 111. Then, in the case of executing the arithmetic processing next, when the arithmetic relation information of the arithmetic processing to be executed matches with the arithmetic relation information stored in the cache memory 111, the arithmetic result stored in the cache memory 111 corresponding to the arithmetic relation information is read. Then, by defining it as the arithmetic result of the arithmetic processing, the overlapping execution to the same arithmetic processing is prevented. |
