$10-$Consider achieving the best performance for the following instructions:

$1$ Add R$4,$ R$2,$ R$3$

$2.$ SW R$5,$ #$100($R$4)$

$3.$ LW R$6,$ #$200($R$4)$

$4.$ Sub R$7,$ R$5,$ R$6$

Assume each stage takes one cycle, the pipeline finishes at:

Select one:

a$.$ cycle $9$

b$.$ cycle $12$

c$.$ cycle $10$

d$.$ cycle $8$

e$.$ cycle $11$

$11-$The instructions

Add R$1,$R$2,$R$3$

Sub R$2,$R$7,$R$3$

And R$5,$R$1,$R$6$

cause data hazards that are:

Select one:

a$.$ WAR and RAW

b$.$ WAR and WAR

c$.$ RAW and WAR and RAW

d$.$ RAW and RAW

e$.$ WAW and WAW

$12-$Consider achieving the best performance for the following instructions:

$1$ Add R$4,$ R$2,$ R$3$

$2.$ SW R$5,$ #$100($R$4)$

$3.$ LW R$6,$ #$200($R$4)$

$4.$ Sub R$7,$ R$5,$ R$6$

the data hazard between $2$ and $4$ are solved by:

Select one:

a$.$ forwarding from Ex in $2$ to mem in $4$

b$.$ forwarding from Mem in $2$ to mem in $4$

c$.$ no data hazards

d$.$ forwarding from Ex in $2$ to Ex in $4$

e$.$ stall
