Hyperdimensional computing hardware:progress,trends and prospects
摘要
Abstract
Hyperdimensional computing(HDC),an emerging computing paradigm drawing inspiration from the human brain,boasts several notable advantages,including low complexity,exceptional robustness,and high interpretability.Consequently,it holds im-mense potential for a wide array of applications in edge-side applications.HDC serves as an innovative approach that mimics the human brains information processing mechanisms.By leveraging hyperdimensional vectors and straightforward logical operations,it can accom-plish complex cognitive functions.Instead of relying on the complicated architecture of neural network with multi-layers,it employs a lightweight encoding-querying process,paving a fresh technical avenue for the development of highly efficient edge-side artificial intelli-gence chips.This review provides a meticulous and in-depth analysis of the theoretical foundations and the progressive development of algorithms within HDC,and thoroughly investigates the viability of implementing hardware acceleration techniques at every step of HDC.Based on this,this review focuses on the dedicated hardware for the querying step,summarizes the three implementation meth-ods of FPGA,ASIC,and in-memory computing,and analyzes the advantages and disadvantages of different methods.Moreover,con-sidering the prevalent shortcomings inherent in existing hardware for hyperdimensional querying,this review presents some most recent research advancements.Finally,the challenges confronting hardware for HDC are delineated,and the promising avenues for its future research endeavors are outlined.关键词
