PURPOSE:To shorten the processing time and to make it unnecessary to provide a large-capacity memory internally, by storing data, which is used latest or is used most frequently, in a temporary storage memory. CONSTITUTION:When a CPU1 requires certain information for a certain processing, this information is searched in a temporary storage memory; and if it is found there, this information is read out to a buffer 3, and the required processing is performed. When this information is returned to the memory 4, it is brought to the start of the memory 4. If required information does not exist in the memory 4, the CPU1 stores this information in the buffer 3 and performs the required processing when this information is obtained by the response from the controller 5. After the processing, the CPU1 stores this information in the start of the memory 4. |
