Abstract
PURPOSE:To decrease the rate at which a desired page is not registered in an address conversion buffer, by registering plural continuous pages in one entry of the address conversion buffer. CONSTITUTION:In one entry of an address conversion buffer, a 2-page portion is contained and the least significant bit 102 of a page number P is used for selecting a page '0' and a page '1' by a selecting circuit 7. At the time of indexing the address conversion buffer 2, the contents of the corresponding entry are read out by a set address 101, and a key part 11 and a comparison address of a logical address register 1 are compared by a comparator 3. When both of them coincide, and also, an effective bit 10 is ON, information corresponding to an address of the logical address register is registered in the address conversion buffer 2. In this case, by a real page number 104 from a selecting circuit 7 and a line address 105 from the logical address register 1, a desired real address is set to a real address register 6. In such a way, a rate at which a desired page is not registered in the address conversion buffer can be decreased.
