2.Power Efficiency. A company has a processor with a peak performance of 8 GFs/s and a power dissipation of 2 W, for a power efficiency of 4 GFs/s/W. Prior to scaling up, the company wants a power efficiency of 32 GFs/s/W. Assume that, independently of processor size, performance is given by pf = k1 * f GFs/s, and power is given by pw = k2 * f^2.25. where 'k1' and 'k2' are constants, and 'f' is the clock frewquency. a) By what factor 'x' must the clock frequency be reduced to achieve the desired power efficiency? x = _________ b) Working with TSMC, the company is trying to shrink transistor (and hence core) size to be able to populate a (multicore) processor chip with many cores. With the new clock frequncy, what (integer) number 'n' of cores must fit on the chip in order to have a peak performance of at least 32 GFs/s? n = _________
