Dynamic Architectural Clock Gating: A Practical Approach to Power Optimization

Author(s) Karthik Wali

Abstract Clock gating is a widely used technique to reduce the power consumption of digital circuits by selectively disabling the clock signal to portions of the circuit when they are not needed. Dynamic architectural clock gating introduces a more adaptive and efficient approach to this technique, integrating both hardware and software strategies for better power management. This paper explores dynamic architectural clock gating (DACG) as a practical approach to optimize power usage in modern processors and integrated circuits. The study highlights the fundamental concepts of DACG, its implementation in different architectural contexts, and its effectiveness in reducing dynamic power consumption. The paper discusses the methodology for implementing DACG in modern processors and compares its performance with static clock gating techniques.
DACG offers a substantial reduction in power consumption by dynamically adapting the clock signal based on runtime data, leading to more effective energy management than traditional clock gating methods. The study provides experimental results demonstrating that DACG can achieve significant power savings while maintaining minimal performance degradation. By integrating both software algorithms and hardware architecture modifications, DACG proves to be an essential tool for energy-efficient system design in the age of multi-core processors and high-performance computing. Additionally, the research highlights challenges associated with implementing DACG, including balancing power savings with performance trade-offs and addressing hardware overheads.
Experimental results show that DACG offers substantial power savings with minimal impact on performance, making it a promising solution for energy-efficient system design in various application domains, including mobile devices, servers, and embedded systems.
