Looking for core that does a vector product

Hi Andrew,

That's going to cost a lot of internal signals. However, this is easy to write yourself. Just use two arrays, Coeff and Input, and use a for loop to go through the array saying Result := Result + (Coeff(index) * Input(index))

Good luck!

Core?, isn't this a multiplier, an accumulator, coef table, data table & a sequencer or am I missing something? Sounds like it could be run off in the time it takes to read the core documentation.

This looks very similar to convolution. I suggest looking at cores that can do this.

It is basically an FIR core with the delay queue stripped off. Which device family? What is the data rate? If you don't have, don't have enough or don't want to use the embedded multipliers, you can also use a distributed arithmetic approach. One of the advantages of not relying on the xilinx cores is that somethinglike this is easily extracted from the existing library.
