Abstract

PURPOSE:To acquire only the memory of the part that is needed for analysis of a failure for a memory dump device which writes the memory contents into a file. CONSTITUTION:The device control programs 21, 22 and 23 include the dump programs 51, 52 and 53 respectively. The start address of the dump program included in a desired device control program is previously registered in a dump program register table 3. When a memory dump device is started, the memory dump operations are carried out in the order of registration.
