Abstract

A method for processing interrupt requests in a processor is suitable for executing at least two threads in parallel, wherein an instruction pipeline is provided for each of the at least two threads. One of the at least two threads is defined as a main thread for processing programs. Another thread of the at least two threads is assigned to the main thread as an interrupt thread. After an interrupt request is received, the processor stores interrupt data in a register assigned to the interrupt thread. Subsequently, the processing of an interrupt routine is started in the interrupt thread and at least part of the interrupt routine is executed in the interrupt thread.
