Cache block size (b) can affect both miss rate and miss latency. assuming a machine with a base cpi of 1, and an average of 1.35 references (both instruction and data) per instruction, find the block size that minimizes the total miss latency given the ollowing miss rates for various block sizes.

8: 4% 16: 3% 32: 2% 63: 1.5% 128: 1%
a.) what is the optimal block size for a miss latency of 20 × b cycles?

b.) what is the optimal block size for a miss latency of 24 + b cycles?

c.) for constant miss latency, wha
t is the optimal block size?

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

Ashielded metal arc-welding operation is accomplished in a work cell by a fitter and a welder. the fitter takes 5.5 min to load components into the welding fixture at the beginning of the work cycle, and 1.5 min to unload the completed weldment at the end of the cycle. the total ength of the weld seams 1200 mm, and the travel speed used by the welder averages 300 mm/min. every 600 mm of seam length, the welding stick must be changed, which takes 0.8 min. while the fitter is working, the welder is idle (resting): and while the welder is working the fitter is idle. (a) determine the average arc-on time as a fraction of the work cycle time. (b) how much improvement in arc-on time would result if the welder used flux-cored arc welding (manually operated), given that the spool of weld wire must be changed every 10 weldments, and it takes the welder 5.0 min to accomplish the change? (c) what are the production rates for these two cases (weldments completed per hour)? attach your work and solutions.
