ABSTRACT:
In a processor system, different memory means (8), which can in each case comprise a memory stack (9) for the instruction counter, a register (10) for temporarily storing data and status register (11), are provided for various tasks. When an interrupt event (EV) occurs which causes a change from a current task to a new task, a controller (21) switches from the memory means (8) allocated to the old task to the memory means (8) allocated to the new task.
