1. In Exercise 4.12, we are analyzing the cost/complexity/performance trade-offs of forwarding in a pipelined processor. We assume that a fraction of instructions have a particular type of RAW data dependence, identified by the stage that produces the result (EX or MEM) and the instruction that consumes the result (1st instruction that follows the one that produces the result, 2nd instruction that follows, or both).
2. To determine the fraction of cycles stalling due to data hazards without forwarding, we need to consider the probability of each type of dependence causing a stall. From the given hazard probabilities and pipeline stage latencies, we can calculate the probabilities as follows:
- EX to 2nd: 0.15 (15%)
- MEM to 2nd: 0.05 (5%)
- EX to 1st: 0.10 (10%)
- MEM to 1st: 0.10 (10%)
To calculate the total fraction of cycles stalling due to data hazards, we add up the probabilities of each type of dependence causing a stall and multiply by the CPI of the processor:
0.15 + 0.05 + 0.10 + 0.10 = 0.40 (40%)
Therefore, if we use no forwarding, 40% of cycles are stalling due to data hazards.
3. To determine the fraction of cycles stalling due to data hazards with full forwarding, we assume that all results that can be forwarded are forwarded. This means that only the "MEM to 1st" dependence can cause a stall. Therefore, the fraction of cycles stalling due to data hazards with full forwarding is:
0.10 (10%)
This is a significant improvement over the 40% stalling fraction without forwarding.
4. If we cannot afford to have three-input muxes for full forwarding, we need to decide whether to forward only from the EX/MEM pipeline register (next-cycle forwarding) or only from the MEM/WB pipeline register (two-cycle forwarding). To determine which option results in fewer data stall cycles, we need to consider the probabilities of each type of dependence causing a stall with each option.
- Next-cycle forwarding: Only the "MEM to 1st" dependence can cause a stall, so the fraction of cycles stalling due to data hazards is 0.10 (10%).
- Two-cycle forwarding: The "EX to 1st" and "MEM to 1st" dependences can cause a stall, so the fraction of cycles stalling due to data hazards is:
0.10 + 0.10 = 0.20 (20%)
Therefore, next-cycle forwarding results in fewer data stall cycles.
5. Finally, we need to calculate the speedup achieved by adding full forwarding to a pipeline that had no forwarding. We can calculate the speedup as follows:
Speedup = 1 / (1 - fraction of cycles stalling due to data hazards)
With no forwarding, the fraction of cycles stalling due to data hazards is 0.40 (40%), so the speedup is:
Speedup = 1 / (1 - 0.40) = 1.67 (67%)
This means that adding full forwarding can improve performance by up to 67%.

For a PTC with a rim angle of 80º, aperture of 5.2 m, and receiver diameter of 50 mm,
determine the concentration ratio and the length of the parabolic surface.
The concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.
To determine the concentration ratio and length of the parabolic surface for a Parabolic Trough Collector (PTC) with the given parameters, we can use the following formulas:
Concentration Ratio (CR) = Rim Angle / Aperture Angle
Length of Parabolic Surface (L) = Aperture^{2} / (16 * Focal Length)
First, let's calculate the concentration ratio:
Given:
Rim Angle (θ) = 80º
Aperture Angle (α) = 5.2 m
Concentration Ratio (CR) = 80º / 5.2 m
Converting the rim angle from degrees to radians:
θ_rad = 80º * (π / 180º)
CR = θ_rad / α
Next, let's calculate the length of the parabolic surface:
Given:
Aperture (A) = 5.2 m
Receiver Diameter (D) = 50 mm = 0.05 m
Focal Length (F) = A^{2} / (16 * D)
L = A^{2} / (16 * F)
Now we can substitute the given values into the formulas:
CR =\((80º * (π / 180º)) / 5.2 m\)
L = \((5.2 m)^2 / (16 * (5.2 m)^2 / (16 * 0.05 m))\)
Simplifying the equations:
CR ≈ 1.48
L ≈ 5.2 m
Therefore, the concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile at a constant acceleration of 1.96 m/s2. The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s2. (Hint: The police will not go against the law.) a) Find the total time required for the police car to overtake the automobile. (12 marks) b) Find the total distance travelled by the police car while overtaking the automobile. (2 marks) c) Find the speed of the police car at the time it overtakes the automobile
Answer:
A.) Time = 17.13 seconds
B.) Distance = 31.9 m
C.) V = 11.18 m/s
D.) V = 7.1 m/s
Explanation:
The initial velocity U of the automobile is 15.65 m/s.
At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile with initial velocity U = 0 at a constant acceleration of 1.96 m/s². Because the police is starting from rest.
For the automobile, let us use first equation of motion
V = U - at.
Acceleration a is negative since it is decelerating with a = 3.05 m/s² . And
V = 0.
Substitute U and a into the formula
0 = 15.65 - 3.05t
15.65 = 3.05t
t = 15.65/3.05
t = 5.13 seconds
But the motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s².
The total time required for the police car to overtake the automobile will be
12 + 5.13 = 17.13 seconds.
b.) Using the third equation of motion formula for the police car at V = 11.18 m/s and a = 1.96 m/s²
V^2 = U^2 + 2aS
Where S = distance travelled.
Substitute V and a into the formula
11.18^2 = 0 + 2 × 1.96 ×S
124.99 = 3.92S
S = 124.99/3.92
S = 31.88 m
c.) The speed of the police car at the time it overtakes the automobile will be in line with the speed zone which is 11.18 m/s
d.) That will be the final velocity V of the automobile car.
We will use third equation of motion to solve that.
V^2 = U^2 + 2as
V^2 = 15.65^2 - 2 × 3.05 × 31.88
V^2 = 244.9225 - 194.468
V = sqrt( 50.4545)
V = 7.1 m/s

Which wheel alignment term describes the way that the front wheels align themselves with the rear wheels when the car is moving in straight line
Answer:
Thrust angle
Explanation:
The term that describes the way that the front wheels align themselves with the rear wheels when the car is moving in a straight line is called "thrust angle."
Thrust angle refers to the angle between the geometric centerline of the rear axle and the centerline of the vehicle. When a vehicle is properly aligned, the thrust angle should be parallel to the vehicle's centerline, which ensures that the front wheels are also aligned with the rear wheels and the vehicle moves in a straight line.
However, if the thrust angle is not properly aligned, the front wheels will not track straight ahead and the vehicle may pull to one side or the other. In these cases, a wheel alignment service may be necessary to adjust the thrust angle and ensure proper alignment.
