18-Bit x 18-Bit Multipliers
Introduction
A Virtex-II multiplier block is an 18-bit by 18-bit 2’s comple-
ment signed multiplier. Virtex-II devices incorporate many
embedded multiplier blocks. These multipliers can be asso-
ciated with an 18 Kbit block SelectRAM resource or can be
used independently. They are optimized for high-speed
operations and have a lower power consumption compared
to an 18-bit x 18-bit multiplier in slices.
Each SelectRAM memory and multiplier block is tied to four
switch matrices, as shown in
