Research introduces Idle-Waiting strategy for energy-efficient FPGA-based DL accelerators in IoT

ai-technology · 2026-04-22

A new study has introduced an Idle-Waiting strategy that offers a promising alternative to turning off FPGA-based deep learning accelerators when they're not in use. Instead of focusing on saving energy during the inference phase, this approach emphasizes the FPGA's configuration stage. Researchers achieved a significant 40.13-fold reduction in configuration energy by tweaking certain parameters. When paired with other energy-efficient methods, Idle-Waiting outperformed conventional On-Off techniques for request lengths of up to 499.06 ms in duty-cycle mode. For a 40 ms request within a 4147 J energy budget, it can extend system life nearly 12.39 times more than the On-Off method. This research, aimed at enhancing energy efficiency for IoT applications, is available under arXiv:2407.12027v2.
