Abstract
An 8×8 binary digital multiplier reduces the height of partial product columns to be no more than 7 bits high. The six 7-bit high middle columns are each input to a (7:3) counter. An ascending triangle compressor operates on the lesser significant bit columns. A descending triangle compressor operates on the greater significant bit columns. The counter and compressor outputs are combined for a final stage of compression, followed by partial product addition.
