处理器的电源必须在包括轻负载在内的各种条件下保持高效。迄今为止,为了提高CPU电源的效率,提出了自适应功率效率控制方法,该方法涉及功率控制与处理器逻辑数据处理工作负载的自适应互锁。结果表明,使用这种方法可以提高CPU电源的功率效率。然而,该方法的效率提高尚未通过实验验证。在本研究中,该方法被应用在一个硬件实验中,以验证处理器电源效率的提高。结果表明,该方法可以提高电源效率,降低电能损耗。
The power supply for a processor must remain highly efficient over a wide range of conditions, including light loads. To date, to improve the efficiency of CPU power supplies, the adaptive power efficiency control method, which involves adaptively interlocking power control with processor logical data processing workloads, was proposed. It was shown that improved power efficiency of the CPU power supply was possible using this method. However, the efficiency improvement of the method has not yet been verified through experiments. In this study, the method was applied in a hardware experiment to verify the efficiency improvement of the processor power supply. The results showed that the method could improve power efficiency and reduce power loss.
