I need help with this problem and an explanation of the solution for the image described below. (Introduction to Signals and Systems)
Given a microprocessor with the following specifications and a program consisting of 60 billion instructions, calculate the energy consumption and efficiency for each operating mode. Base Frequency Mode: 2 GHz at 1 V • Turbo Mode: 3 GHz at 1.2 V • CPI = 2.5 • Static Power (Pstatic): 5 Watts ⚫ Dynamic Power Metrics - a = 0.5 (Activity Factor) - C=100nF (Capacitance) Show the detailed calculations for: (1) the wall clock runtime of the program in both modes, and show the speedup of Turbo Mode compared to Base Mode; (2) the total power consumption; and (3) the energy consumption. (Hint: To obtain the energy consumption, you will first need to compute the metrics for items (1) and (2).)
If X is uniformly distributed over (0, 1) and Y is exponentially distributed with parameter A = 1, and X and Y are independent, find the pdf of Z = X + Y.
