TARNA: A 1.18-μW/Channel Topology-Aware Residual Recurrent CIM Processor for Zero-Shot Seizure Detection

2026

Abstract

Zero-shot seizure detection avoids patient-specific training but remains challenging under strict power constraints and patient variability. This work presents TARNA, a topologyaware recurrent network accelerator implemented as an ultra-low-power computing-in-memory (CIM) zero-shot seizure detector. TARNA combines graph convolutions with masked residual recurrent updates to eliminate nonlinear gating, while a sparsity-aware CIM macro further reduces energy. Fabricated in 65−nm CMOS, TARNA achieves 100 % zeroshot event-based sensitivity and a 0.048/hr false-alarm rate on the CHB-MIT dataset, and an AUROC of 0.88 on the TUSZ dataset, operating at the lowest reported power of 22.5μ W.

Efficient energy use

Efficient energy use, sometimes simply called energy efficiency, is the process of reducing the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs, fluorescent lighting, or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs.

Energy conservation

Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings.

Sustainable energy

Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Most definitions of sustainable energy include considerations of environmental aspects such as greenhouse gas emissions and social and economic aspects such as energy poverty. Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy are generally far more sustainable than fossil fuel sources.
