Calculate sum of (WAR, RAW and WAW) dependencies instructions.
Consider the following instructions. I 1 : R 1 = 100 I 2 : R 1 = R 2 + R 4 I 3 : R 2 = R 4 + 25 I 4 : R 4 = R 1 + R 3 I 5 : R 1 = R 1 + 30 Calculate sum of (WAR, RAW and WAW) dependencies the above instructions. (a) 10 (c) 6 (b) 12 (d) 8

If asked to count the number of RAW dependencies, do we consider only adjacent instructions or both adjacent and non-adjacent? Please explain in detail.

For relation R=(L, M, N, O, P), the following dependencies hold: M→O, NO→P, P→Land L→MN R is decomposed into R1 = (L, M, N, P) and R2 = (M, O).What is the highest normal form satisfied by the above decomposition? My doubt is For R1 it is in 2NF and R2 it is in BCNF .But ,dependency preserving also violates .So whts the highest normal form ?

Test by Bikram | Computer Organization and Architecture | Test 2 | Question: 26
Which of the following statements is/are correct about hazards? One way to implement branch prediction is to store the result of a branch condition in a branch target buffer to help guide instruction pre-fetching if the branch is ... whether the branch is taken. III only II and III only I and III only I, II, and III

GATE IT 2007 | Question: 39
Data forwarding techniques can be used to speed up the operation in presence of data dependencies. Consider the following replacements of LHS with RHS. $R1→ Loc, Loc→ R2 \quad ≡ R1→ R2, R1 → Loc$ $R1→ Loc, Loc→ R2 \quad ≡ R1→ R2$ ... RHS be the same as executing the LHS irrespective of the instructions that follow ? i and iii i and iv ii and iii ii and iv
