IPC: G06F12/10
Filed: 1987-05-14
Abstract: PURPOSE:To shorten a processing time by using a physical address by a converting mechanism only when the page number of a logical address to be converted is different from a held page number. CONSTITUTION:When an instruction logical address comparator 4 detects a discrepancy between the page number held in an instruction logical address register 3 and the page number of an instruction logical address supplied currently through a logical address bus (d), an instruction address conversion instruction signal line 4a is made active. Then an instruction physical address register 6 holds the output of a page register storage circuit 1 and an instruction logical address register 3 holds the page number of the current instruction logical address. Further, when the contents of the instruction logical address register 3 are equal to the high-order digit address of the current logical address, an instruction logical address comparator 4 does not make the instruction address conversion instruction signal line 4a active and the physical address which is converted before and held in the instruction physical address register 6 is held effective continuously. Consequently, the processing speed is improved.
