16 x 16 PARALLEL CMOS MULTIPLIER-ACCUMULATOR
DESCRIPTION (Continued)
either a multiply or a multiply-accumulate function. In the
multiply-accumulate mode, output data can be added to or
subtracted from previous 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 a single precision or single precision
plus 3-bit extended result. In the multiply mode, the Extended
PIN CONFIGURATIONS
The Accumulate input (ACC) enables the device to perform

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 Preload 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.
