Challenge Problems
Push your limits with advanced challenges
You are tasked with designing a VLSI circuit for a battery-operated device. Propose a clock gating strategy that could save power and explain your rationale.
💡 Hint: Think about which components in your device might remain idle during operation.
A circuit consumes 80 mw when fully active. If the implementation of gate-level power optimization reduces the switching activity by 40%, calculate the new power consumption and provide a brief explanation.
💡 Hint: Focus on understanding the percentage impacts on overall power consumption.
