2.1 System Generator for DSP - When does the multiplier block use embedded Virtex-II pipelined multipliers?


Keywords: SysGen, MATLAB, Simulink, xlmult, multiplier generator, MULT18X18S

Urgency: Standard

General Description:
When I use a multiplier block, I notice that the embedded Virtex-II pipelined multipliers are used on occasion. What criteria determines when these multipliers are used?


The Xilinx Block Set Multiplier will use the embedded Virtex-II pipelined multiplier when one of the inputs is greater than 19 bits.

The option for "pipelining" must also be selected.
