Assume that the technology scales every two years by a factor of SA. If a microprocessor in year 2000 is dissipating 100W, consider a scaling scenario in the future, where all the dimensions scale by a factor of B every technology generation. Technology generation spans 2 years. Assume also that the trends from the past will continue in the future as well: the microprocessor die size continues to increase by C every other year, the supply voltage is reduced by a factor D and frequency doubles every technology generation. Find the power dissipation of a future microprocessor in year 2008. Please write down all of your assumptions and explain your reasoning. A, B, C, D are known
