Problem 1

A.

The first one is Personal mobile device (PMD), $100-$1000 of system and $10-$100 of microprocessor. Its critical system design issues is cost, energy, media performance and responsiveness.

The second one is Desktop, which system in it values $300-$2500 and microprocessor values $50-$500. Desktop focus on Price-performance, energy and graphics performance.

The third one is Server, it will cost $5000-$10,000,000 in system and $200-$2000 in microprocessor. Its goal is throughput, availability, scalability and energy.

The fourth one is Clusters/warehouse-scale computer, which is more expensive than Server in system, often we should cost $100,000-$200,000,000 in it. But the price of microprocessor is cheaper than Server, which values $50-$250. These computers are more interested in price-performance, throughput and energy proportionality.

The last one is Embedded, in which the price of system varies from $10 to $100,000 and from $0.01 to $100 when talking about microprocessor. Its critical system design issues is price, energy and application-specific performance.

B.

One type is Data-Level Parallelism, which arises because there are many data items that can be operated on at the same time.

The other type is Task-Level Parallelism, which arises because tasks of work are created that can operate independently and largely in parallel.

Problem 2:

(a).

The formula is but sorry I don’t know N so I can’t calculate.

(b).

The manufacturing size and the die size of Power5 is larger than Niagara and Opteron, so the difference of technology result in the lower defect rate.

2.

(a).

Profit = (area of per wafer/area of chip)*profit per chip

= (150^2*pi/150)*20

= $9424.78

(b).

Profit = (area of per wafer/area of chip)*profit per chip

= (150^2*pi/250)*25

= $7068.58

(c).

I should produce Woods chip for I can earn more per wafer.

Problem 3:

1.

(a).

If each component is the maximum load, then the Pentium 4 will use...
