A 54- $\\mu$ W Design-Agnostic Clock, Voltage, and EM-Pulse Fault-Injection Attack Detection Using Time-to-Voltage Conversion 150 150
Author(s): Yudhajit Ray, Archisman Ghosh, Sarthak Antal, Shreyas Sen

Abstract:

This article presents a state-of-the-art design-agnostic clock, voltage, and electromagnetic pulse (EMP)-based fault-injection attack (FIA) detector. The efficient conversion of time-to-voltage information by integrating amplifiers transforms the time anomaly into the voltage domain, enabling its detection at a lower power consumption. The clock-glitch detector design consumes only $53~\mu $ W …

Abstract:

Bit-serial computation enables sequential processing of data at the bit level, providing several advantages, such as scalable computational precision. This approach has gained significant attention, especially for exploiting bit-level sparsity (BLS) in AI workloads. While current bit-serial processors leverage BLS to eliminate the computation associated with zero bits, they face …

Author(s): Rentao Wan, Chuan-Tung Lin, Bo Zhang, Yannis Tsividis, Mingoo Seok

Abstract:

This article presents an analog-in analog-out CIM macro (AACIM) for use in analog deep neural network (DNN) processors. Our macro receives analog inputs, performs a 64-by-32 vector–matrix multiplication (VMM) with a current-discharging computation mechanism, and produces analog outputs. It stores a 4-bit weight as an analog voltage in the …
