Row
Each row block provides 18 bits of data to the multiplier (i.e., one of the
operands to the multiplier), which are routed through the 30 local
interconnects within each DSP row interface block. Any signal in the
device can be the source of the 18-bit multiplier data, by connecting to the
local row interconnect through any row or column.
Each control signal routes through one of the eight rows of the DSP block.

routes.
Input/Output Data Interface Routing
The 30 local interconnects generate the 18 inputs to the row interface
blocks. The 21 outputs of the row interface block are the inputs to the DSP
row block (see
DSP block-wide signed and unsigned control signals for all multipliers.
The multiplier outputs are unsigned only if both

Controls addition or subtraction of the two one-level adders. The

signal controls the bottom two one-level adders. A high indicates
addition; a low indicates subtraction.
Resets the feedback input to the accumulator. The signal

begin without losing any clock cycles. The
