PURPOSE:To realize an access to whole physical space of a main storage, by providing a location register for fetching instruction that is capable of direct addressing to the physical space of the main storage and an address conversion table. CONSTITUTION:A system is equipped with a location register 3 able to directly address the physical space of a main storage, and an address conversion table 4 which converts a logic space into a physical space in terms of address, in addition, a memory address register 9 showing the position of the logic space for an access of the data. A data processor in addition to these units, includes a main storage device 1, an instruction register 10 that sets the instruction read out of the device 1, and a data buffer register 11 that sets the data read out of the device 1 or extracts the data which is written into the main storage 1. |
