Abstract

This paper presents a scalable neural-network (NN) inference accelerator in 16nm, based on an array of programmable cores employing mixed-signal In-Memory Computing (IMC), digital Near-Memory Computing (NMC), and localized buffering/control. IMC achieves high energy efficiency and throughput for matrix-vector multiplications (MVMs), which dominate NNs; but, scalability poses numerous challenges, both technologically, going to advanced nodes to maintain gains over digital architectures, and architecturally, for full execution of diverse NNs. Recent demonstrations have explored integrating IMC in programmable processors [1, 2], but have not achieved IMC efficiency and throughput for full executions. The central challenge is drastically different physical design points and associated tradeoffs incurred by IMC compared to digital engines. Namely, IMC substantially increases compute energy efficiency and HW density/parallelism, but retains the overheads of HW virtualization (state and data swapping/buffering/communication across spatial/temporal computation mappings). The demonstrated architecture is co-designed with SW-mapping algorithms (encapsulated in a custom graph compiler), to provide efficiency across a broad range of mapping strategies, to overcome these overheads.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
