Find the number of clock cycles required to execute the instruction sequence given below if the system given in Figure 4.62 of the textbook is used. Assume branch BEQ is taken. (20 points)

add $3, $1, $2

or $4, $2, $3

beq $1, $2, 2 (Note: 2 is the offset of the BEQ )

and $1, $4, $2

slt $2, $1, $5

lw $12, 0($18)

sw $12, 4($18)

Find the number of clock cycles required to execute the instruction with register forwarding? Justify your answer

add $3, $1, $2

or $4, $2, $3

and $1, $4, $2

slt $2, $1, $5

lw $2, 100($1)

add $3, $1, $2

lw $4, 100($2)

and $1, $4, $2

slt $2, $1, $5
