Abstract
PURPOSE: To symprify the constitution of whole system, reduce the load of CPU and increase the processing speed by writing plural data records on the memory unit in the I/O memory device independently from indication CPU.
CONSTITUTION: When check point data record CR.A is generated, CPU1 writes A, for example, on memory units 9#0, and 9#1. When CR.B and CR.C are generated successively, they are written respectively on units 9#0 and 9#1 in the same manner. Since the memory units have not region which can accept the write request of another CR.A generated from CPU1, any of channel 7, I/O controller 8 and I/O memory device 5 is initiated and 1 block stored in units 9#0 and 9#1, where records A, B and C are stored, is written on device 5#0, for examle, magnetic tape.
