Abstract

PURPOSE:To eliminate an insertion of an uninspected instruction into the instruction row for a programmer, by continuing a process based on the storage contents of the subsequent segment that detected that the instruction row exceeded the range of the divided segments. CONSTITUTION:For a computer having the address space divided into plural segments, the uncoincidence signal is applied to the virtual storage control part 14 in case the subject process segment of the instruction address counter 2 does not exist in the associative storage 3. Then the segment information is recorded in the storage 3 as well as in the range storage 4 and the subsequent segment storage 5 respectively. When the fact that the indication of the counter 2 is more than the segments in the storage 4 is detected, each segment of the counter 2 is set based on the contents of the storage 5 via the range detector 9 and the device 14. Then the control is transferred to the head instruction of the subsequent segment, and thus an instruction row covering plural segment is carried out with no insertion of the branch instruction. In the same way, a repetitive process or the like of the instruction is carried out in a high speed.
