Abstract:

Heterogeneous 3D compute-in-memory (CiM) architectures have emerged as an efficient acceleration paradigm for deep neural network (DNN) inference by leveraging the complementary characteristics of diverse memory technologies enabled through 3D integration. Prior work has focused on architectural efficiency and workload-mapping optimization, leaving the security implications of heterogeneous CiM systems largely …

Abstract:

This letter presents a novel hardware accelerator compatible with <3- $\mu $ m pitch 3-D Cu-Cu hybrid bonding interconnect (HBI) technology, particularly designed to efficiently execute multihead attention (MHA) of encoder transformer models. We present an accelerator that addresses performance losses due to low precision models by incorporating specialized hardware optimizations …
