In Al-edge devices, the changes of input features are normally progressive or occasional, e.g., abnormal surveillance, hence reprocessing unchanged data consumes a tremendously redundant amount energy. Computing-in-memory (CIM) directly executes matrix-vector multiplications (MVMs) in memory, eliminating costly movement energy deep neural networks (DNNs) [2–6]. Prior CIM work only explored sparsity DNNs to improve efficiency, but trend employing non-sparse activation functions, leaky ReLU,...
Argonaute (Ago) proteins are ubiquitous across all kingdoms of life. Eukaryotic Agos (eAgos) use small RNAs to recognize transcripts for RNA silencing in eukaryotes. In contrast, the functions prokaryotic counterparts (pAgo) less well known. Recently, short pAgos conjunction with associated TIR or Sir2 (SPARTA SPARSA) were found serve as antiviral systems combat phage infections. Herein, we present cryo-EM structures nicotinamide adenine dinucleotide (NAD

Aimed at the limitation that existing hyperspectral classification methods were mainly oriented to small-scale images, this paper proposed a new large-scale remote sensing image method, LS3EU-Net++ (Lightweight Encoder and Integrated Spatial Spectral Squeeze Excitation U-Net++). The method optimized U-Net++ architecture by introducing lightweight encoder combining (S3E) Attention Module, which maintained powerful feature extraction capability while significantly reducing training cost. In...
IoT devices usually operate in random-sparse-event scenarios (Fig. 20.2.1). To avoid missing events, traditionally a periodic-wake-up frequency [1] must be orders of magnitude higher than the average event rate, wasting huge power. An emerging event-driven approach seeks to trigger power-hungry high-performance system (HPS) using an ultra-low-power wake-up circuit. State-of-the-art chips with DSP-based and neural-network-based feature extraction consume 12nW [2], 1μW [3], 142nW [4]. However,...
Power is a major bottleneck in AIoT devices, which usually operate random-sparse-event (RSE) scenarios [1] (Fig. 12.1.1, bottom). To process RSEs energy-efficiently, one can integrate an always-on wake-up chip [1-5] that only turns on the power-hungry high-performance system (HPS) once valid events are detected. Previous dedicated voice-activity-detection (VAD) chips using analog front-ends (AFE) followed by neural-network (NN) circuits consume 1μW [2] and 142nW [3]. Keyword spotting (KWS)...
This article presents a 148-nW always-on wake-up system that drastically reduces the power consumption of Internet Things (IoT) sensor nodes while oftentimes operating in random-sparse-event (RSE) scenarios. To significantly reduce long-term average (LTA) and realize multiapplication intelligent event detection, three techniques are proposed: 1) In three-stage pipelined event-driven architecture, frame generator convolutional neural network inference engine (CNN IIE) stage III by preliminary...
Human brain is a natural ultimate-event-driven (UED) system with low power and real-time response-ability, thanks to the asynchronous propagation processing of spikes. Power dissipation latency are major concerns in AloT devices, usually operating random-sparse-event (RSE) scenarios (Fig. 22.7.1, top). Being event-driven on level, an always-on wake-up (WUS) detects valid RSEs energy-efficiently intelligently, upon detection turns power-hungry high-performance (HPS). module prior WUS [1] uses...

Steep sub-threshold interband tunnel field-effect transistors (TFETs) are promising candidates for low-supply voltage applications with better performance than the traditional complementary metal oxide semiconductor (CMOS). However, some of shortcomings TFETs also severely limit their application. From device perspective, studies have been conducted on in order to improve performance. Instead, this study focuses following four challenges from perspective circuit design: (1) uncontrollable...
