Query: MIMHD: Accurate and Efficient Hyperdimensional Inference Using Multi-Bit
  In-Memory Computing   Hyperdimensional Computing (HDC) is an emerging computational framework that
mimics important brain functions by operating over high-dimensional vectors,
called hypervectors (HVs). In-memory computing implementations of HDC are
desirable since they can significantly reduce data transfer overheads. All
existing in-memory HDC platforms consider binary HVs where each dimension is
represented with a single bit. However, utilizing multi-bit HVs allows HDC to
achieve acceptable accuracies in lower dimensions which in turn leads to higher
energy efficiencies. Thus, we propose a highly accurate and efficient multi-bit
in-memory HDC inference platform called MIMHD. MIMHD supports multi-bit
operations using ferroelectric field-effect transistor (FeFET) crossbar arrays
for multiply-and-add and FeFET multi-bit content-addressable memories for
associative search. We also introduce a novel hardware-aware retraining
framework (HWART) that trains the HDC model to learn to work with MIMHD. For
six popular datasets and 4000 dimension HVs, MIMHD using 3-bit (2-bit)
precision HVs achieves (i) average accuracies of 92.6% (88.9%) which is 8.5%
(4.8%) higher than binary implementations; (ii) 84.1x (78.6x) energy
improvement over a GPU, and (iii) 38.4x (34.3x) speedup over a GPU,
respectively. The 3-bit $\times$ is 4.3x and 13x faster and more
energy-efficient than binary HDC accelerators while achieving similar
accuracies.
