MASSIVELY PARALLEL, ASSOCIATIVE MULTIPLIER-ACCUMULATOR

Abstract:

An in-memory multiplier-accumulator includes a memory array, a multi-bit multiplier and a multi-bit layered adder. The memory array has a multiplicity of rows and columns, each column being divided into a plurality of bit line processors and each bit line processor operating on its associated pair of input values. The multi-bit multiplier utilizes each bit line processor to multiply the associated pair of input values in each bit line processor to generate multiplication results. The multi-bit layered adder accumulates the multiplication results of each column of bit line processors.
