HMA510GM-55883
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 plement 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 latched on the rising edge of the associated clock signal. The 35-bit Accumulator Output Register is broken into three parts. The 16-bit least significant product (LSP), the 16-bit most significant product (MSP), and the 3-bit extended product (XTP) Registers. The XTP and MSP Registers have dedicated output ports, while the LSP Register shares the Y-inputs in a multiplexed...
