Chapter 1 Solutions
Case Study 1: Chip Fabrication Cost
× –4
a. Yield== 1 + -------------------------
× –4
b. Yield== 1 + ----------------------------
c. The Sun Niagara is substantially larger, since it places 8 cores on a chip rather
than 1.
× –4
a. Yield== 1 + ----------------------------
π× ()30⁄ 2 2 π× 30
Dies per wafer = ------------------------------ –---------------------------------- = 182– = 148
sqrt() 2 ×
$500
Cost per die ==-------------------------- $
148 ×
.7 × –4
b. Yield== 1 + ----------------------
π× ()30⁄ 2 2 π× 30
Dies per wafer = ------------------------------ –---------------------------------- = 380– = 331
sqrt() 2 ×
$500
Cost per die ==----------------------- $
331 × .32
c. $ × .4 = $
d. Selling price = ($ + $) × 2 = $
Profit = $ –$ = $
e. Rate of sale = 3 × 500,000 = 1,500,000/month
Profit = 1,500,000 × $ = $32,310,000
$1,000,000,000/$32,310,000 = 31 months
.75 × ⁄ 8 –4
a. Yield== 1 + --------------------------------
Prob of error== 1–
b. Prob of one defect = × × 8 =
Prob of two defects = × × 28 =
Prob of one or two = × =
c. = .06 (now we see why this method is urate!)

d. ⁄ =
e. x × $150 + × $100 –( × $80) – × $ = $200,000,000
x = 885,938 8-core chips, 8,416,390 chips total
Case Study 2: Power Consumption puter Systems
a. .70x = 79 + 2 × + 2 × = 146
