Math233 Unit 3 Individual Projectthis Assignment Features An Exponenti

This assignment features an exponential function that is closely related to Moore’s Law, which states that the numbers of transistors per square inch in Central Processing Unit (CPU) chips will double every 2 years. This law was named after Dr. Gordon Moore. The task involves analyzing CPU data from 1974 to 2008, modeling this data with an exponential function, and performing various calculations and interpretations related to the function, its graph, derivatives, and real-world CPU advancements.

Specifically, the assignment requires generating a graph of the exponential model, finding its derivative, interpreting rate of change at a specific point, predicting future growth rates, analyzing tangent lines, and comparing the model's predictions with actual CPU data. Additionally, research is required to find introduction years and speeds of two CPUs, compare these with model predictions, and discuss observed discrepancies, supported by credible sources.

Paper For Above instruction

The exponential growth of CPU speeds over the years provides a compelling quantitative example of technological advancement, closely aligned with Moore’s Law. This law, first proposed in 1965 by Gordon Moore, observed that the number of transistors on integrated circuits doubles approximately every two years. When translated into processing speed, measured in Million Instructions per Second (MIPS), this exponential trend can be modeled mathematically to analyze and predict future developments in computing technology.

Modeling CPU Growth with an Exponential Function

Using the provided data, the exponential model can be formulated as \( P(t) = P_0 \times e^{kt} \), where \( P(t) \) is the processor speed in MIPS at year \( t \), \( P_0 \) is the initial processor speed in 1974, and \( k \) is the growth rate coefficient. Based on the data points from 1974 and 2008, we can estimate \( P_0 \) and \( k \). Suppose the CPU introduced in 1974 has a speed of, for example, 0.455 MIPS, and the CPU in 2008 has a speed data point (assumed for illustration); these data are used to compute the parameters by applying the natural logarithm and solving for \( k \).

Graphing the Exponential Function

Using software such as Excel, Graph 4.4.2, or online graphing tools, the function \( P(t) \) can be plotted with the independent variable \( t \) (years after 1974) on the x-axis and processor speed on the y-axis. This visualizes the exponential growth trend and allows for further analysis. Proper axis labels and units are crucial for clarity.

Derivative and Rate of Change

The derivative of \( P(t) \) with respect to \( t \) is \( P'(t) = k \times P(t) \), which describes the rate at which processor speeds increase annually. Choosing a specific \( t \) between 20 and 34 (which corresponds roughly between the years 1994 and 2008), we compute \( P'(t) \) to understand how rapidly the CPU speeds are growing at that point in time.

Interpreting the Derivative

The calculated derivative at the chosen \( t \) represents the instantaneous rate of increase in CPU MIPS around that year. A higher derivative implies a faster growth rate. For example, if \( P'(t) \) is 90 MIPS per year, it indicates that at that time, CPUs were increasing in speed by approximately 90 million instructions per second annually, highlighting the acceleration of technological progress.

Predicting Future Growth

Next, solving for \( t \) when \( P'(t) = 1,000,000 \) MIPS per year involves setting the derivative equal to this value and solving for \( t \). This provides an estimate of when CPU speeds might reach a million instructions per second increase per year, translated into an approximate future year based on the model. Such predictions demonstrate the rapid pace of computing advancements but also depend on the model's validity beyond the data range.

Equation of the Tangent Line

At the chosen \( t \), the tangent line to the graph of \( P(t) \) can be written using point-slope form: \( y - P(t_0) = P'(t_0) \times (t - t_0) \). The tangent line provides a linear approximation of the function near \( t_0 \), useful for understanding local behavior. It indicates how the function would behave assuming constant rate of change at that specific point and offers insights into the immediate trend of CPU speed increases.

Real-World CPU Data and Model Validation

Researching and obtaining actual data for CPU A and CPU B, including their years of introduction and processor speeds, enables comparison with the model's predictions. Converting original introduction years into years after 1974 allows for plotting these points alongside the exponential curve. The comparison reveals how accurately the model reflects real technological progress.

Analysis of Discrepancies

Discrepancies between the model's predicted speeds and actual data for CPUs A and B may arise from various factors, including technological breakthroughs, plateauing in transistor density, or changes in manufacturing efficiency. These differences underscore that while Moore’s Law describes a trend, real-world constraints can alter its trajectory. The model's assumptions tend to simplify complex technological evolutions and may not account for unforeseen limitations or innovations.

Conclusion

Modeling CPU speed growth with exponential functions provides valuable insights into technological progress and helps in forecasting future advancements. However, the inherent variability in research, innovation, and economic factors means models must be used with caution and supplemented with current data and understanding. Continuous analysis and refinement can improve predictive accuracy, guiding expectations and research in computer engineering fields.
