Question:
A nonmaskable interrupt (NMI) is triggered by an input pin to the processor. When the pin is asserted, the current instruction should finish, then the processor should set the Cause register to 0 and take an exception. Show how to modify the multicycle processor in Figures 7.63 and 7.64 to handle nonmaskable interrupts.
