PURPOSE:To reduce the storage capacity of a microinstruction storing means by optionally connecting a storage device port to an arithmetic unit bus by a semi-fixed connecting device, and after starting data processing, fixing the connection. CONSTITUTION:Two ports 16 of respective storage devices 11 can be optionally connected to the ports of two arithmetic units 12 through connection nodes in a key-fixed connection device 13. When connection between an optional bus of the device 13 and an optional port is determined in order to execute a program, node connection can be attained. Before starting processing, the program is statically scheduled, the ports 16 of a necessary storage device 11 are optionally connected to the buses 15 of the arithmetic units 12, and after starting the data processing, control information for connecting the storage device 11 to the arithmetic units 12 is deleted by the device 13 for fixing the connection and the storage capacity of the microinstruction storing means is reduced. |
