Abstract
PURPOSE: To limit and erase the ineffective part of the high speed address conversion buffer, by providing the indirect segment reference bit when a direct designation segment descriptor is altered.
CONSTITUTION: Direct designation segment descriptor DSD.a and indirect designation segment descriptor ISD.b including the pointer information to DSD.a are stored in the main memory unit 1110. The memory buffer unit 1112 outputs the attribute of the segment of ISD.b and the absolute address information of the segment. The indirect segment reference bit (ISR bit) indicating the designation at ISD.b is provided in DSD.a. In response to ISR bit, when DSD.a in the unit 1110 not designated with ISD.b is rewritten, the content of storage of the unit 1112 including the information corresponding to the logic address designating DSD.a is erased.
