Context Before
LPU chip
Groq’s first and only publicly announced LPU architecture was detailed in their ISCA 2020 paper. Unlike typical hardware architectures connecting many general-purpose cores, Groq re-organized the architecture into groups of single-purpose units connecting to other groups of different purposes, and they named the groups “slices.” Between functional units are streaming registers, scratchpad SRAM for functional units to pass data to each other. Groq opted for single-level scratchpad SRAM instead of multi-level memory hierarchy to make the hardware execution deterministic.
Evidence
Spatially, the slices are laid out horizontally, allowing the data to stream horizontally

② Atomic Claim
關於 LPU：在空間配置上，這些 slices 水平排列，使資料可以水平方向串流。
