ABSTRACT:
An address translation apparatus is provided which has an address translation look-aside buffer with an entry composed of a real address field, virtual machine identifier field and space identifier field. For the translation look-aside buffer entry to be used by a general virtual machine which uses a plurality of address spaces, a virtual machine identifier for discrimination of a general virtual machine is stored in the virtual machine identifier field, and information used in discriminating an address space is stored in the space identifier field. For the translation look-aside buffer entry to be used by a dynamic address translation off (DATOFF virtual) machine which uses a single address space, an identifier commonly assigned to a group of DATOFF virtual machines is stored in the virtual machine identifier field, and a control block address used in discriminating a DATOFF virtual machine is stored in the space identifier field.
