Abstract
A neural network accelerator is disclosed that includes a multiplication unit, an adder-tree unit and an accumulator unit. The multiplication unit and the adder tree unit are configured to perform lattice-multiplication operations. The accumulator unit is coupled to an output of the adder tree to form dot-product values from the lattice-multiplication operations performed by the multiplication unit and the adder tree unit. The multiplication unit includes n multiplier units that perform lattice-multiplication-based operations and output product values. Each multiplier unit includes a plurality of multipliers. Each multiplier unit receives first and second multiplicands that each include a most significant nibble (MSN) and a least significant nibble (LSN). The multipliers in each multiplier unit receive different combinations of the MSNs and the LSNs of the multiplicands. The multiplication unit and the adder can provide mixed-precision dot-product computations.
