[sdiy] FPGA multiplier

[jbv]

This one if for FPGA gurus :
if I need to implement a 16 x 16 bits logic
multiplier with 32 parallel outputs and latched
i/o on Xilinx or Altera systems, what kind of
chip am I supposed to use ?
The question concerns actually the type of chip
(package, number of pins, size, PCB room) that
can be used. I'd like to compare with existing
multiplier chips...

Thanks,
JB
