If the control system has dedicated ALUs and with the new data path included, an

alternative general ALU is available that will run additions $($and subtractions$)$ in half the

time $($ex: $120$ps vs$.240$ps$)$ but non$-$addition ALU operations now take a stall as

processing time overhead. What would be the total speedup with all improvements of the

pipelined system if $80\%$ of ALU operations were additions?
