Document Type and Number:
Japanese Patent JP3921751
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize the prompt processing of data change by pending the data writing to a disk while the changed data is present thereby reducing the number of the writing.
SOLUTION: At the step S6, the CPU compares the data written into the area 1 of the SRAM with the data in the DRAM at the time of this step 86 and thereby making it judge whether there is changed data or not, namely whether the data of the DRAM has been changed while the processing from steps 1 to 6 is conducted. When there is changed data, the data of the area 1 is copied to the area 2 of the SRAM, processing is returned to step 1 and processing from step S1 to S6 is repeated until there is no changed data at step S6. After that, processing is advanced to step S8 and the succeeding steps and writing of data to the disk is made at step S10.
