An instruction format has the following structure:
Instruction Number: Opcode destination reg, source reg-$1$, source reg-$2$
Consider the following sequence of instructions to be executed in a pipelined processor:
$\text{I 1: DIV R3, R1, R2}$
$\text{I 2: SUB R5, R3, R4}$
$\text{I 3: ADD R3, R5, R6}$
$\text{I 4: MUL R7, R3, R8}$
Which of the following statements is/are TRUE?
- There is a RAW dependency on $\text{R 3}$ between $\text{I 1}$ and $\text{I 2}$
- There is a WAR dependency on $\text{R 3}$ between $\text{I 1}$ and $\text{I 3}$
- There is a RAW dependency on $\text{R 3}$ between $\text{I 2}$ and $\text{I 3}$
- There is a WAW dependency on $\text{R 3}$ between $\text{I 3}$ and $\text{I 4}$
