pipelining
We have two designs P 1 and P 2 for a synchronous pipeline processor. P1 has 8 pipeline stages with execution time of 3 nsec, 2 nsec, 4 nsec, 7 nsec, 2 nsec, 5 nsec, 4 nsec and 2 nsec while design P2 has 5 stages each with 6 nsec execution time. How much time can be saved using design P2 over design P1 for executing 400 instructions?

congestion control
Consider the effect of using slow start on a line with 10 msec round trip time. The receiver window and the size of congestion window are set to 38 KB and 36 KB respectively. Sender side threshold is set to 18 KB. After 8 transmission a time-out occurs, ... to send first full window of 18 KB is____________ (in msec). Assume window size at the start of slow start phase is 2 KB.
