    • The present invention provides a data processing system having excellent immediacy of interrupting process. Different interrupt request signals are supplied from a circuit module which can be commonly used by a plurality of central processing units to a plurality of interrupt controllers assigned to central processing units, respectively. In response to the input interrupt request signal, each of the interrupt controllers notifies the corresponding central processing unit of an interrupt. The circuit module selects an interrupt controller for supplying an interrupt request signal from the plural interrupt controllers. For example, the circuit module identifies a central processing unit which instructed a start request and supplies an interrupt request signal to an interrupt controller corresponding to the central processing unit. The burden of the interrupting process of the single central processing unit can be lessened. In addition, since the interrupting process in the single central processing unit is not necessary, interruption response of another central processing unit is increased.
