Description: Energy management in FPGAs (Field Programmable Gate Arrays) refers to the techniques and strategies implemented to optimize and reduce energy consumption in these devices. Since FPGAs are widely used in applications requiring intensive processing and flexibility, energy efficiency has become a crucial aspect of their design and operation. Energy management techniques include dynamic voltage and frequency scaling (DVFS), powering down inactive blocks, and using low-power architectures. These strategies allow designers to maximize performance while minimizing energy consumption, which is especially important in portable applications and embedded systems where battery life is critical. Energy management not only contributes to environmental sustainability by reducing resource consumption but also enhances the reliability and lifespan of devices. In a world where the demand for data processing continues to grow, efficient energy management in FPGAs has become an active research area and a determining factor in the choice of this technology for various applications.
