Optical Flow Sensor: A Direction-Selective Bionic Retina Design
Juchen Zhou, Bonan Yan, Yuchao Yang
Optical flow characterizes motion in the visual field and is fundamental to motion perception and tracking in biological and artificial vision systems. Biological retinas extract m…
Efficient SRAM-PIM Co-design by Joint Exploration of Value-Level and Bit-Level Sparsity
Cenlin Duan, Jianlei Yang, Yikun Wang +7
Processing-in-memory (PIM) is a transformative architectural paradigm designed to overcome the Von Neumann bottleneck. Among PIM architectures, digital SRAM-PIM emerges as a promis…
Non-Binary LDPC Arithmetic Error Correction For Processing-in-Memory
Daijing Shi, Yihang Zhu, Anjunyi Fan +3
Processing-in-memory (PIM) based on emerging devices such as memristors is more vulnerable to noise than traditional memories, due to the physical non-idealities and complex operat…
Towards Efficient SRAM-PIM Architecture Design by Exploiting Unstructured Bit-Level Sparsity
Cenlin Duan, Jianlei Yang, Yiou Wang +7
Bit-level sparsity in neural network models harbors immense untapped potential. Eliminating redundant calculations of randomly distributed zero-bits significantly boosts computatio…
