Abstract

PURPOSE: To prevent lowering in the usage efficiency of buffer accompanied with the selection of space and to increase the processing efficiency, by using the address conversion buffers of a plurality selectively through the discrimination whether the access logic address belongs to the common virtual space or not.
CONSTITUTION: The address conversion buffers TTB2, 3, 4 and 5 registrating the conversion pair of the logic address and real address, and means 12W15 discriminating whether the access address is in common virtual space or not, are provided. Further, TTB2 and 3 perform address conversion depending on the function between the present space identifier 18 and the logical address, and TTB4 and 5 perform the address conversion depending on the function of logic address. Further, if the access addresses S and P are not present at the common virtual space, TTB2 and 3 are used and if present in the common virtual space, TTB4 and 5 are used to obtain the real address corresponding to the logical address.
