If we know that the processor has a stuck$-$at$-1$ fault on

this signal, is the processor still usable? To be usable, we must be able to convert

any program that executes on a normal MIPS processor into a program that works

on this processor. You can assume that there is enough free instruction memory

and data memory to let you make the program longer and store additional

data. Hint: the processor is usable if every instruction $$broken$$ by this fault can

be replaced with a sequence of $$working$$ instructions that achieve the same

effect.
