PURPOSE:To prevent deterioration in the performance of an information processor in TLB trouble by adding the value corresponding to the instruction length of a real address by an adder when a real display bit indicates the real address, and setting it as the next real address in an instruction counter. CONSTITUTION:When an address commanded to an IC11 is a logical address, the off signal of the real display bit 21 is sent to a control circuit to cause an interruption to a microprogram under its control, and the found real address is set in the IC11 to turn on the real display bit 21. Then, when an advance of the program is made continuously, an ADD13 adds the instruction length to the contents of the IC11 and the result is set as the next address in the IC11. When the contents of the IC11 increases by said addition up to the next page, a carry signal is supplied to the digit indicating the page of the ADD13, so an OR gate 23 receives the signal to output a page cross signal. Thus, an MS/BS14 is read out by the real address and the processing of the information processor is performed by the read instruction. |
