ABSTRACT:
Within a superscalar processor implementing parallel processing of instructions, machine context synchronization operations, which may alter the context or state of the processor, are allowed to be executed in parallel with non-interruptible instructions under certain conditions. Such a condition includes the absence of a side effect of the change of context resulting from the machine context synchronization operations on the non-interruptible instructions.
