PURPOSE:To avoid the deterioration in throughput and profitability due to a fact that a load is concentrated on a specific processor by carrying out the saving/restoring processes of information used by plural processors after decentralizing these processes to each processor. CONSTITUTION:A saving means 300 extracts information D out of a corresponding individual memory 2 and stores it in a saving area 22 of another individual memory 200. A restoring means 400 extracts the saving information stored in the memory 22 and stores it in the corresponding memory 2. Therefore, the information used by processors 1 and 100 are saved and restored decentralizedly by both processors 1 and 100. Thus the load is not concentrated on a specific processor and therefore the throughput is not deteriorated. Furthermore, the memory capacity is never increased with both memories 2 and 200 and therefore the deterioration in profitability is prevented. |
