Abstract

PURPOSE: To quickly cope with an external instruction by reading directly the data equal to (n) sectors out of a memory with no access given to a disk in case a reading instruction is received for the data equal to (n) sectors following the data equal to (m) sectors.
CONSTITUTION: The data is written into a memory 6 with a reading instruction and at the same time the sector number of the data is written into a memory control table 8. Thus the data equal to (m) sectors (m≥1) is read out of the k-th sector with an external reading instruction. In this respect, the variable (j) of a program of a CPU 9 is set at (k). Then it is checked whether the sector number of j = k is written into the table 8 or not, that is, whether this sector number is read out before or not. If so, the data on the sector number is read out of the memory 6 and sent to the outside. Thus it is possible to know via the table 8 that the data if once read out of a disk 5 is written into the memory 6. Then the data c an be quickly read out of the memory 6 with no access given to the disk 5.
