1.3 20/201 Your colleague at AMD suggests that, since the yield is so poor, you might make chips more cheaply if you released multiple versions of the same chip, just with different numbers of cores. For example, you could sell Phoenix Phoenix4, Phoenix2, and Phoenix1, which contain 8, 4, 2, and 1 cores on each chip, respectively. If all eight cores are defect-free, then it is sold as Phoenix8. Chips with four to seven defect-free cores are sold as Phoenix, and those with two or three defect-free cores are sold as Phoenix. For simplification, calculate the yield for a single core as the yield for a chip that is 1/8 the area of the original Phoenix chijp Then view that yield as an independent probability of a single core being defect free. Calculate the yield for each configuration as the probability of at the corre sponding number of cores being defect free a. [20] What is the yield for a single core being defect free as well as the yield for Phoenix4, Phoenix2 and Phoenix1? would be worthwhile to package and sell, and why will be the cost of the new Phoenix chips, assuming that there are no additional b. [5] Using your results from part a, determine which chips you think it c. [10] If it previously cost $20 dollars per chip to produce Phoenix8, what costs associated with rescuing them from the trash? 1.3 20/201 Your colleague at AMD suggests that, since the yield is so poor, you might make chips more cheaply if you released multiple versions of the same chip, just with different numbers of cores.
