Abstract
Abstract Disclosed is a multi-processor system in which central processing units (10,20) each provided with a main storage unit (13,23), an extended storage unit (14,24), an instruction processor (11,21) for making access to the main storage unit (13,23) or extended storage unit (14,24) through a storage control unit (12,22), and the storage control unit containing an interface control (15,25) for making communication between one central processing unit and another central processing unit are coupled with each other through the interface control, in which each of the central processing unit is operable by an independent operating system. In this system, the operating system for each of the instruction processor (11,21) permits an access to the extended storage unit (14,24) or each of the central processing units by specifying an identification number set for the extended storage unit thereof. This enables the extended storage unit to be shared in the system because the extended storage unit is accessible directly from each of the central processing units.
