HiRo: A Compact Four-Directional Hierarchical Reservoir Token-Mixer for Efficient Image Classification
Md Farhadul Islam, Ishan Thakkar, J. Todd Hastings
Recent image classification models must balance local feature modeling, cross-window interaction, and parameter efficiency. Many high-performing architectures rely on fully trainab…
Scaling Photonic Tensor Cores with Unary and Homodyne Designs
Oluwaseun Alo, Ishan Thakkar
We analyze five photonic microring tensor core designs with a common optical power model. The results show that circuit ordering, unary encoding, and homodyne accumulation shape sc…
Sustainable Transformer Neural Network Acceleration with Stochastic Photonic Computing
S. Afifi, O. Alo, I. Thakkar +1
Transformers achieve state-of-the-art performance in natural language processing, vision, and scientific computing, but demand high computation and memory. To address these challen…
HEANA: A Hybrid Time-Amplitude Analog Optical Accelerator with Flexible Dataflows for Energy-Efficient CNN Inference
Sairam Sri Vatsavai, Venkata Sai Praneeth Karempudi, Ishan Thakkar
Several photonic microring resonators (MRRs) based analog accelerators have been proposed to accelerate the inference of integer-quantized CNNs with remarkably higher throughput an…
Mixed Delay/Nondelay Embeddings Based Neuromorphic Computing with Patterned Nanomagnet Arrays
Changpeng Ti, Usman Hassan, Sairam Sri Vatsavai +8
Patterned nanomagnet arrays (PNAs) have been shown to exhibit a strong geometrically frustrated dipole interaction. Some PNAs have also shown emergent domain wall dynamics. Previou…
SafeLight: Enhancing Security in Optical Convolutional Neural Network Accelerators
Salma Afifi, Ishan Thakkar, Sudeep Pasricha
The rapid proliferation of deep learning has revolutionized computing hardware, driving innovations to improve computationally expensive multiply-and-accumulate operations in deep…
