Question on Pipelining
In a pipeline the maximum ideal speed-up is 5. Let the percentage of unconditional branches in a set of typical program be 5% and that of conditional branches be 10%. If 70% of the conditional branches are taken, calculate % loss of speed-up due to branch instructions. It is very difficult to understand this question and solve it. Please help.

Automatic Repeat Request
Consider an ARQ algorithm running over a 20-km point-to-point fiber link. (a) Compute the propagation delay for this link, assuming that the speed of light is 2 × 10^8 m/s in the fiber. (b) Suggest a suitable timeout value for the ARQ algorithm to use. (c) Why might it still be possible for the ARQ algorithm to time out and retransmit a frame, given this timeout value?
