CS136 Homework #1

See calendar for due date.

Do problems 1.3 through 1.7 in the book.

Notes on the problems:

You're welcome to use whatever resources you choose (Google, library, etc.) for looking up formulas and such.
For problem 1.3a, the "defect rate" to use is the information from line 2 of table 1.22. The yield equation is given elsewhere in the book; if you've done the reading you shouldn't have difficulty finding it.
For problem 1.3e, note that the cost is per die sold, not per die manufactured.
On problem 1.5a, be sure to include the power supply. Use the same power-supply efficiency as in 1.4a. Note that the power supply's waste heat must be dissipated by the cooling door.
On problem 1.5c, assume two hard drives per processor (RAID-1), one power supply per rack, and a MTTR for disks of 24 hours.
On problem 1.7c, the voltage floor is 70% of the original voltage, not 30%. In other words, if the original voltage was 5V, the reduced voltage would have to be 3.5V or more.
