Editing Stack machine (section)

=== Interrupts ===
Responding to an interrupt involves saving the registers to a stack, and then branching to the interrupt handler code. Often stack machines respond more quickly to interrupts, because most parameters are already on a stack and there is no need to push them there. Some register machines deal with this by having multiple register files that can be instantly swapped<ref name="Intel_1980"/> but this increases costs and slows down the register file.
