Following Question 3 and given the design assumptions, which types of programs are better suited for Turbo
Mode in terms of power/energy consumption? (Hint: From a microprocessor design perspective, identify the
values that are fixed in the power computation equation and the parameter that varies with different programs.)
Also, provide a specific example where Turbo Mode would be more beneficial.
Given:
Static power, Pstatic = 5 W
• Dynamic power for Base Frequency Mode, Pdynamic_base
2 x 109 Hz= 100 W
aCVasefbase = 0.5 × 100 × 10−⁹ F × (1 V)² ×
• Dynamic power for Turbo Mode, Pdynamic_turbo = αCV turbofturbo = 0.5 × 100 × 10−9 F × (1.2 V)² × 3 ×
109 Hz =
216 W
