PURPOSE:To improve the processing capability of a processor by providing two buffers, an address conversion buffer in a processor chip and an address conversion buffer at the outside of the processor chip. CONSTITUTION:Even when no objective address conversion information exists in the address conversion buffer 2 in the processor chip, when the information exists in the address conversion buffer 7 at the outside of the processor chip, since the information is used for registration on an address conversion buffer in the processor chip and for address conversion, the address conversion processing is applied at a high speed. Moreover, the entry number and the constitution of the address conversion buffer 2 in processor chip are decided independently, the rate of indexing the address conversion list on the memory in case of the address conversion is reduced without giving affect on the processor chip by increasing the number of entries of the address conversion buffer 7 at the outside of the processor chip.
