In
Four-Multiplier Adder is shown as the chainout adder for clarity. This scheme is used
to chain and add multiple DSP blocks together. The output of the chainout adder can
be registered. The registered chainout output can feed the lower adjacent DSP block
for a chainout summation or it can feed general FPGA routing. The chainout result
can be zeroed out by applying logic 1 on the dynamic zerochainout signal. The
zerochainout signal can also be registered.
