FPGA: High-throughput Multiply vs. Multiply

[linu95k]

Does High-throughput Multiply have any additional benefits of drawbacks to standard multiplication function inside SCTL in Labview FPGA?

How do I decide when to use which?

Note: I have a code which is using 100% of my DSP48s on my Crio-9076. From what I understand DSP48s are used majorly in multiplication operations. I am trying to optimize resource usage.

Hi,

Basically, the high-throughput multiply acts faster (even compared with SCTL + standard multiplication function). This function supports only scalar and array values of the fixed-point data type. The advantages are provided in this document (one of which is pipelining, the standard multiplication function hasn't).

Hope the information was useful.

Wish you all the best.
