    摘要： 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).
