Abstract:

This article presents SHINSAI—a 586 mm2 reusable active through-silicon via (TSV) interposer addressing key challenges in multi-chiplet integration (MCI) architectures. While active interposers overcome fundamental limitations of passive counterparts by integrating functional circuitry, existing solutions face three critical constraints: 1) non-recurring engineering (NRE) costs from application-specific interposers negating chiplet reuse benefits; 2) …

Beyond Backside Power: Backside Signal Routing as Technology Booster for Standard-Cell Scaling

Beyond Backside Power: Backside Signal Routing as Technology Booster for Standard-Cell Scaling 150 150
Author(s): Anup Ashok Kedilaya, Sirish Oruganti, Nishant Gupta, Xiuhao Zhang, Ilya Karpov, Mark A. Anders, Jaydeep P. Kulkarni

Abstract:

Advances in process technology enabling backside metals (BSMs) and contacts offer new design–technology co-optimization (DTCO) opportunities to further enhance power, performance, and area gains (PPA) in sub-3-nm nodes. This work exploits backside (BS) contact technology within standard cells to extend both signal and clock routing to BSM layers, …

ROZK: An Energy-Efficient DNN Accelerator Based on Reconfigurable NoC and Local Zero-Skipping

ROZK: An Energy-Efficient DNN Accelerator Based on Reconfigurable NoC and Local Zero-Skipping 150 150
Author(s): Heetak Kim, Yunpyo Hong, Byungsoo Kim, Jongsun Park

Abstract:

Zero-skipping is a famous technique to improve the energy efficiency of deep neural network (DNN) accelerators. When the zero-skipping is realized with encoded data using lossless compression, irregular and unpredictable size of data due to inconsistent compression rate incurs several design issues including: 1) load imbalance from irregularity of data stored …
