Problem $1$:

Translate the following RISC$-$V function F$1$ into machine code both in binary and hexadecimal:

F$1$: addi $x2,x2,-4$

Sw $x22,0(x2)$

lui $x22,1022$

ori $x22,x22,124$

blt $x21,x22,L1$

add $x23,x20,x20$

beq $x7,x7,Ex$

sub $x23,x20,x20$

lw $x22,0(x2)$

addi $x2,x2,4$

jalr $x0,O(x1)$

If a caller uses the instruction:

jal x$1,$ F$1$

residing at address $8420$ to call the $F1$ function residing at address $2024$ and if the values of $x1,x2,x7,x20,x21,$

$x22,$ and x$23$ were $1200,6000,134,-32,385,-738,$ and $1100$ respectively at call time, what would be their final

values at return time? Also, what will be the value of $22$ immediately after the execution of the ori instruction?
