Consider a hypothetical pipeline processor with the following characteristics: It has a $5-$stage pipeline: Instruction Fetch $($IF$),$ Instruction Decode $($ID$),$ Execution $($EX$),$ Memory Access $($MEM$),$ and Write Back $($WB$).$ The processor employs a dynamic two$-$bit branch predictor with a saturating counter $(00,01,10,11).$ The predictor starts in the $01$ state $($predict not taken$)$ for all branches. Branch instructions are resolved in the EX stage. The processor has a loop buffer that can store and quickly execute up to four recently executed instructions in a loop, bypassing the usual IF stage for these instructions. Given the following loop in a program: loop$\_$start: add r$1,$ r$2,$ r$3$ sub r$4,$ r$5,$ r$6$ beq r$7,$ r$0,$ loop$\_$end nop j loop$\_$start loop$\_$end: Each instruction takes one
