Challenge Problems
Push your limits with advanced challenges
A circuit uses 100mW when fully active, and clock gating allows for a 40% reduction during idle states. Calculate the new power consumption during idle.
💡 Hint: Use the percentage reduction to find out how much power can be saved.
Discuss the implications of using outdated techniques (like DVFS) in modern high-performance applications that demand consistent performance and explain how designers might need to pivot.
💡 Hint: Consider the balance between performance and power when discussing alternatives.
