Computer Internal Components and Structure

need help with the following questions!

1.

What are four major differences in design considerations for embedded vs mobile processors? There are many more than four possible answers.

2.

What is the role of a bus in computer architecture, an example might be the front side bus on your motherboard, or a universal serial bus (USB).

3.

List 3 reasons why have we seen a shift to multi-core processors rather than faster and faster single monolithic core designs?

4.

Given the memory latency of the 3 components below, match A, B and C as well as possible to the following components: CPU cache, RAM, and 'non volatile storage' (i.e. a hard drive) .

Memory latency Component which corresponds to that latency: (fill in right column)

A 1ns

B 150ms

C 10ns

5.

Given examples of when response time or throughput are more appropriate measures used to compare two processors?

6.

For a given benchmarking program (that executes a fixed number of instructions) explain how an Intel CPU with a clock speed of 2.3 GHz could outperform an AMD CPU with a clock speed of 4GHz (single thread, single CPU, and yes, a real Pentium G630T @2.3GHz is faster than an A10-7870k at 3GHz, barely).

7.

Because the numbers aren't nice and even, just derive or show the equation that would allow you to calculate what frequency the AMD CPU in question 6 would need to be to match the Intel CPU IPS, but you don't need to try and resolve the calculation.

8.

Typical air-cooling solutions range in heat dissipation performance from about 4.5 watts to 140 watts. A typical mid range processor dissipates about 90 watts, and a high-end version from the same processor family dissipates around 140w. These processors have the same capacitive load but operate at different voltages and frequencies (typically 1.2 volts for mid range, 1.4 for high end). Derive an equation to show what the difference in frequencies might be between these processors (hint, this is the same equation as the power wall, except now we know Pnew and Pold, and don't know Fnew or Fold).

9.

For a given CPU integer operations a+b, and a*b take almost identical amounts of time, for floating point (32 bit) multiplication takes approximately 3x as long. Floating point additions and integer additions take nearly identical times. (Yes, those are nearly real numbers for Intel Haswell CPU's). For a program that is 20% logic operations (which take the same no matter what), 40% additions and 40% multiplications, derive a formula to calculate the estimated performance of changing the maths from Integer to Floating point operations on the same CPU
