Multiple interrupt request data is stored in a queue and handled by a single interrupt sub-routine to provide a batch handling capability to maximize the interrupt handling efficiency of a microprocessor. Events are organized into groups having a common interrupt handling requirement and a data storage queue is provided for each group. At least one data word is stored for each event requiring interrupt attention in a respective queue. An interrupt handling routine upon a single call handles all data words within a queue before exiting the interrupt handling routine.
