Adder/Output Blocks
The result of the multiplier sub-blocks are sent to the adder/output block
which consist of an adder/subtractor/accumulator unit, summation unit,
output select multiplexer, and output registers. The results are used to
configure the adder/output block as a pure output, accumulator, a simple
two-multiplier adder, four-multiplier adder, or final stage of the 36-bit
multiplier. You can configure the adder/output block to use output
registers in any mode, and must use output registers for the accumulator.
The system cannot use adder/output blocks independently of the
multiplier.
