Abstract
A data processing system is provided which includes a central processing unit connected to a memory and a plurality of peripheral units. When a single peripheral request is issued from one of the plurality of peripheral units for a processing which includes a process to be executed a plurality of times, an interrupt control section which holds mode information indicating whether the currently set mode is a Macro Service processing mode, outputs the mode information in response to the peripheral request issued from the peripheral unit. An execution section which is contained in the central processing unit executes the processing while determining whether the process is completed for a predetermined number of cycles in a state suspending at least a program counter and program status word without saving them in the stack, when the mode information indicates the Macro Service processing mode.
