Abstract
A novel energy-efficient multiplication circuit using analog multipliers and adders reduces the distance data has to move and the number of times the data has to be moved when performing matrix multiplications in the analog domain. The multiplication circuit is tailored to bitwise multiply the innermost product of a rearranged matrix formula to output the generate a matrix multiplication result in form of a current that is then digitized for further processing.
