A device for performing multiply/accumulate operations processes values in first and second buffers and having a first width using a computational pipeline with a second width, such as half the first width. A sequencer processes combinations of portions (high-high, low-low, high-low, low-high) of the values in the first and second buffers using a multiply/accumulate circuit and adds the accumulated result of each combination of portions to a group accumulator. Adding to the group accumulator may be preceded by left shifting the accumulated result (the first width for the high-high combination and the second width for the low-high and high-low combination).

Enhanced multiply accumulate device for neural networks

A circuit for performing multiply/accumulate operations evaluates a type of each value of a pair of input values. Signed values are split into sign and magnitude. One or more pairs of arguments are input to a multiplier such that the arguments have fewer bits than the magnitude of signed values or unsigned values. This may include splitting input values into multiple arguments and inputting multiple pairs of arguments to the multiplier for a single pair of input values.
