Create an ‘overflow’

output port

— — On or Off Overflow port for the

accumulator

Add [] extra latency to

the multiplier output

EXTRA_

MULTIPLIER_

LATENCY

— 0, 1, 2, 3, 4, 5, 6,

7, 8, or 12

Specifies the number of

clock cycles of latency

for the multiplier

portion of the DSP

block. If the

MULTIPLIER_REG

parameter is specified,

then the specified clock

port is used to add the

latency.
