PURPOSE:To attain the correct check of a reference bit although no access reaches to a real memory by setting the reference bit when a dynamic address conversion is closed. CONSTITUTION:A dynamic address conversion mechanism DAT10 produces a real address set to a logical address register 4 to use the real address for actual execution of hardware. Therefore a program step PURGE TLB is set as a new program step, and an address conversion buffer TLB9 is invalidated with the execution of said new program step. As a result, a new logical address is converted into a real address by the DAT10 in the next step. When this conversion is over, a bit R is set to a reference bit memory 12. |
