Abstract

PURPOSE:To prevent the deterioration of processing capacity for a processor, by providing newly a transfer bus between a memory and a file and thus securing an independent transfer between an optional block of the memory and the file. CONSTITUTION:A transfer of data is carried out via a bus 22 between a memory 23 consisting of memory blocks 23a-23c and a processor 21. The transfer of data between the memory 23 and a file 26 is carried out independently from the transfer of data between the memory 23 and the processor 21 and between the block 23a and the file 26 after cutting off an optional block such as 23a from the bus 22 via a bus control circuit 24a and then connecting the cut-off block to a bus 27. When the processor 21 gives an access to the block 23a, an interruption signal is produced or the block 23a is connected to the bus 22 and then to the bus 27 again after an end of transfer of data to the processor 21. In such a way, a discontinuation is not required for the transfer of data between a processor and a memory during a transfer between a memory and a file. Accordingly the deterioration of processing capacity of a processor due to a bus holding can be prevented.
