answer the following questions 1. The following is a question about the command pipeline. Draw a timing diagram in case a jump occurs as a result of conditional branch execution under the conditions below. condition : 1) The pipeline consists of 5 stages (FI, DI, FO, EI, WO) 3) Only instruction #4 (I#4) is a conditional branch instruction 4) When a branch occurs, the branched instruction is I#50. 2. The above pipeline processor clocks 2 GHz and executes a program consisting of 10 million instructions. Instructions are sent out at a rate of one per clock cycle, and the percentage of branch instructions is 20% of the total, assuming the penalty is an average of 3 clocks per branch instruction. How much is (Speedup)? 3. Describe three typical pipeline hazards that interfere with the ideal pipeline flow in the command pipeline.
