Energy-Efficient Embedded Systems Design Using Low-Power FPGA Architectures
Main Article Content
Abstract
Energy-efficient embedded systems design has become crucial, particularly in low-power FPGA architectures,
which must optimize energy consumption while maintaining high computational efficiency. This research aims to explore
advanced strategies for minimizing power usage in FPGA-based systems, without compromising performance. Current
FPGA architectures face several issues, including high dynamic power consumption, inefficient use of logic blocks, and
limited adaptability to fluctuating workloads. These challenges result in suboptimal energy efficiency, especially in
applications requiring long operational lifespans. The proposed methodology focuses on leveraging dynamic voltage and
frequency scaling (DVFS) and power gating techniques to reduce energy consumption in real-time, enabling systems to
adapt to workload variations. Additionally, architectural improvements, such as custom logic block design and optimized
routing paths, are implemented to further enhance energy efficiency. These innovations allow for greater flexibility and
scalability, addressing the limitations present in conventional FPGA designs. Initial findings show that by incorporating
these energy-efficient techniques, the system can achieve power savings of up to 30% compared to traditional designs,
while maintaining or even improving overall performance. This outcome should be especially significant in battery
operated or resource-constrained environments, where energy efficiency is paramount. Achievements in this research not
only highlight substantial energy savings but also improved adaptability, making this approach a must for future FPGA
development.
