Description

The HMA510 is a high speed, low power CMOS 16 x 16-bit

parallel multiplier accumulator capable of operating at 45ns

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 pre-

loading 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 signifi-

cant 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 fash-

ion. The entire 35-bit Accumulator Output Register may be

preloaded at any time through the use of the bidirectional

output ports and the preloaded control.
