Just trying to understand:
what will be the answer?
How this can be a title of the question ? - Sad to see how gate aspirants are thinking that this can be the title. Moverover, does that mean aspirants are just curious to get the answer instead of trying, posting the exact doubt and get the help from community.

What is the meaning of tbb-coa-1 tag ? - if it is just duplicating the questions in test-byb-bikram - that is not allowed, here. — Shaik Masthan, Jan 20

RAW- Read-After-Write Dependencies

WAR-Write-After-Read Dependencies

Two types of dependencies that effect the pipelined-execution in the computer system,

we need to check the consequent instructions for such dependencies.

WAR- I2 and I3 (R1); I2 and I5 (R3)

RAW- I1 and I2(R1); I2 and I3(R2); I3 and I4(R1); I3 and I5(R1); I2 and I5(R2); I5 and I6 (R3)

Total= WAR (2) + RAW (6)

= 8.

Whenever the dependencies occur, stall might be possible in-between the pipelined-execution, leading in degradation of system performance.
