PURPOSE:To change the priority of access, by changing the interruption priority to each processing processor specified according to the state of data processing progress. CONSTITUTION:When a managing processor 16 detects that the processing state of the 2nd processor 18 is behind than that of the 1st processor 17, the priority definning and selection signal set to a selection register 21 is set to a block 23-1 selection signal of a sub-memory 23. The priority is changed so that the 2nd processor 18 can access a main memory unit 2 with the highest priority. Thus, the processing speed in the 2nd processor 18 can be improved. |
