Question $1[30$ points$]$

Given the following MIPS assembly program that is executing in a single$-$cycle processor. The program is stored in the memory address location starting at $0$x$04001248.$

$```$

lui $a$0,0$xA$003$

ori $a$0,$ $a$0,1234$

Start: addi $t$0,$ $zero, $30$

s$1$ti $v$0,$ $t$0,50$

beq $v$0,$ $zero, exit

s$11$ $t$3,$ $t$0,2$

add $t$3,$ $a$0,$ $t$3$

$1$w $t$3,0($$t$3)$

add $t$1,$ $t$1,$ $t$3$

addi $t$0,$ $t$0,1$

j Start

Exit: add $v$0,$ $t$1,$ $zero

jr $ra

$```$

$($a$)$ During the $\backslash (5^\{\backslash$text $\{$th $\}\},7^\{\backslash$text $\{$th $\}\}\backslash )$ and $\backslash (8^\{\backslash$text $\{$th $\}\}\backslash )$ time cycle, determine which instruction is being executed in the single$-$cycle processor? $[3$ points$]$

$($b$)$ Based on the answer in part $($a$),$ highlight the datapath in the single$-$cycle processor

$($c$)$ Using the diagram below, determine the values for signals A$,$ B$,$ C$,$ D$,$ E$,$ F$,$ and G based on the instructions in part $($a$)[$Please ensure the signal width is same as the bus width.$]$

$($d$)$ Determine the $9$ control signals for the instructions in part $($a$)$ that are being executed in the signal$-$cycle processor. $[$Note: For don't care signal, please used symbol $"\backslash ($ X $\backslash )"$ to represent$]$
