HMA510/883 April 1997 16 x 16-Bit CMOS Parallel Multiplier Accumulator Description The HMA510/883 is a high speed, low power CMOS 16 x 16-bit parallel multiplier accumulator capable of operating at 55ns clocked multiply-accumulate cycles.
The 16-bit X and Y operands may be specified as either two’s complement or unsigned magnitude format.
Additional inputs are provided for the accumulator functions which include: loading the accumulator with the current product, adding or subtracting the accumulator contents and the current product, and preloading the Accumulator Registers from the external inputs.
All inputs and outputs are registered.
The registers are all positive edge triggered, and are ...
