For the given instructions, all type of data dependencies(RAW, WAW, WAR) are present.
STORE R1, 0[R2]
LOAD R5, 24[R8]
STORE R3, -8[R9]
Then which of the following is true?
- a)RAW exists if R2 == (R8+24) and WAR exists if R8 == (R9 – 8)
- b)WAW exists if R2 == (R8+24) and WAR exists if (R2+0) == (R9 – 8)
- c)WAW exists if (R8+24) == (R9 – 8) and WAR exists if (R2+0) == (R9 – 8)
- d)RAW exists if (R2+0) == (R8 + 24) WAW exists if (R2+0) == (R9 – 8)
Correct answer is option 'D'. Can you explain this answer?

-8)
b)RAW exists if R2 == (R8 24) and WAW exists if R8 == (R9 -8)
c)RAW exists if R2 == (R8 24) and WAR exists if R8 == (R9 -8)
d)WAW exists if R2 == (R8 24) and WAR exists if R8 == (R9 -8)
The correct answer is d) WAW exists if R2 == (R8 24) and WAR exists if R8 == (R9 -8)
Explanation:
- RAW (Read After Write) dependency occurs when one instruction reads a value that was written by another instruction before it. In this case, there are no dependencies of this type.
- WAW (Write After Write) dependency occurs when two instructions write to the same location in memory. In this case, there is a potential WAW dependency between the first and third instructions since they both write to memory location 0[R2]. However, since the value of R2 is not specified, we cannot determine if this dependency actually exists.
- WAR (Write After Read) dependency occurs when one instruction writes to a location in memory that will be read by another instruction. In this case, there is a potential WAR dependency between the second and third instructions since the second instruction reads from memory location 24[R8] and the third instruction writes to memory location -8[R9]. However, since the values of R8 and R9 are not specified, we cannot determine if this dependency actually exists.
b)RAW exists if R2 == (R8 24) and WAW exists if R8 == (R9 -8)
c)RAW exists if R2 == (R8 24) and WAR exists if R8 == (R9 -8)
d)WAW exists if R2 == (R8 24) and WAR exists if R8 == (R9 -8)
The correct answer is d) WAW exists if R2 == (R8 24) and WAR exists if R8 == (R9 -8)
