PARALLEL CMOS MULTIPLIER-ACCUMULATOR
DESCRIPTION (CONT'D)
three output registers-extended product (XTP), most signifi-
cant product (MSP) and least significant product (LSP)-are
controlled by the respective TSX, TSM and TSL input lines.
The LSP output can be routed through YIN ports in the IDT7210.
The accumulate input (ACC) enables the device to perform
either a multiply or a multiply-accumulate function. In the mul-
tiply-accumulate mode, output data can be added to or sub-
tracted from subsequent results. When the subtraction (SUB)
input is active simultaneously with an active ACC, a subtraction
can be performed. The double precision accumulated result is

rounded down to either asingle precision or single precision plus
3-bit extended result. In the multiply mode, the extended product
output (XTP) is sign extended in the two's complement mode, or
set to zero in the unsigned mode. The ROUND (RND) control
rounds up the most significant product (MSP) and the 3-bit
extended product (XTP) outputs. When pre-load input (PREL) is
active, all the output buffers are forced into a high-impedance
state (see PRELOAD truth table) and external data can be loaded
into the output register by using the TSX, TSL and TSM signals as
input controls.
