$1.)$Convert the following MIPS assembly codes into machine language. Write the

instructions in hexadecimal.

a$.$ add $t$0,$ $s$0,$ $s$1$

b$.$ lw $t$0,0$x$20($$t$7)$

c$.$ addi $s$0,$ $$0,-10$

d$.$ addi $s$0,$ $$0,73$

e$.$ sw $t$1,-7($$t$2)$

f$.$ sub $t$1,$ $s$7,$ $s$2$

$2.)$ For the above assembly codes,

a$.$ Identify which instructions are R$-$type and which instructions are I$-$type.

b$.$ For each I$-$type instruction, sign$-$extend the $16-$bit immediate so that it becomes a $32-$bit number. Write the $32-$bit number in hexadecimal.

$3.)$ Convert the following machine language into assembly codes.

a$.0$x$8$C$0$A$0020$

b$.0$x$2268$FFF$4$

c$.0$x$02328020$

d$.0$x$016$D$4022$
