DATA PROCESSING SYSTEM USING ADDRESS CONVERSION

摘要

An address selector is connected to an address bus, a memory and an input/output unit. A physical address is fed to the memory from an address converter without any modification of the address. Logical addresses are fed to the memory from the input/output unit via a second address converter. Pref. the address selector contains a circuit to select either the physical address from the first converter or the logical address from the input/output unit depending on the value of a given address bit on the address bit.
