Locations / Organization
Multiplier organization is identical to the 18 Kbit SelectRAM
organization, because each multiplier is associated with an
18 Kbit block SelectRAM resource.
In addition to the built-in multiplier blocks, the CLB elements
have dedicated logic to implement efficient multipliers in
logic. (Refer to Configurable Logic Blocks (CLBs)).
