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
Concretely, LPU architecture has VXM slices for vector operations, MEM slices for loading/storing data, SXM slices for tensor shape manipulation, and MXM slices for performing matrix multiplication
