Acomputer architect needs to design the pipeline of a new microprocessor. she has an example program with 106 instructions. each instruction takes 600 ps to finish.

a. how long does it take to execute this program on a non-pipelined, single-cycle processor?

b. assume the current state-of-the-art pipeline has 30 stages. assume also that the stages are perfectly balanced. how much speedup will it achieve compared to the non-pipelined processor?

c. realistically, we cannot achieve ideal speedup due to the overhead of implementing pipelining stages (e. g. imperfectly balanced stages, adding pipeline registers, etc). does this overhead affect the instruction latency, instruction throughput, or both? for each metric affected, is the effect significant? why or why not?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
