Abstract
PURPOSE: To omit steps for check to perform an interrupt processing dependent upon high-speed firmware by constituting this system so that the jumping to a corresponding processing routine may be performed without checking interrupt causes and internal state.
CONSTITUTION: In the information processing unit consisting of processor 3 and I/O devices which are connected to bus 1, control memory 2 to store the firmware which regulates the operation of processor 3 is provided, and processor 3 executes arithmetic operations and processings dependently upon the firmware stored in memory 2. Further, interrupt control circuit 4 to control interrupts on a basis of the instruction of processor 3, memory 5 to store the processing routine corresponding to an interrupt cause, and register group 6 to store the address of the interrupt processing routine are provided. Then, processor 3 sets contents of register 2 on a basis of the internal state of the processing unit; and when the interrupt request from the external has come, the jumping to the corresponding processing routine in memory 5 is performed on a basis of contents of register 2.
