Abstract
PURPOSE: To make the transfer from a slave mode to a privileged mode possible independently of calculation to shorten the processing time by controlling a privileged flag and a privileged control flag in the information processing unit.
CONSTITUTION: Instruction execution part 1 which stores the execution result of the instruction fetch instruction from a main memory is connected to AND circuits 2, 6 and 7, OR circuit 3 and privileged flag flip-flop 4 which indicates the operation mode of the unit through signal lines L1 to L5, and is connected to AND circuits 6, 7 and 2, inverter 5, privileged flag filp-flop 4, privileged control flag flip-flop 8 through signal lines L6 and L7.
