fpga high throughput multipliers

[tomnz]

When should you use these multipliers rather than ordinary multiplies? Is there any drawbacks if using these ie do they take more gates to implement?

What about high throughput additions?

Thanks

You might find this link from the help information: Using the High Throughput Math Functions

In particular: "National Instruments recommends that you use the LabVIEW Numeric functions unless you need the benefits that the High Throughput Math functions provide."  I don't know if there's any penalty for using them when not needed.  For additions and multiplies, the major advantage to the high-throughput operations is that you can more easily control pipelining when executing a series of mathematical operations. (EDIT: but if you don't need to pipeline mathematical operations, then there's no benefit.)
