ABSTRACT:
A method and system for increasing the efficiency of execution in a processor. Instructions are dispatched in instruction groups, wherein if such an instruction group contains an interruptible instruction of a selected type, only one interruptible instruction of the selected type is included in the instruction group. A state of the processor is recorded, associated respectively with each of said dispatched instruction groups. The processor is restored to the recorded state associated with the instruction group containing the interruptible instruction of the selected type causing an interrupt, in response to the interrupt from one of the interruptible instructions of the selected type.
